I'm from Australia and can absolutely assure you that huntsman spiders are potentially deadly. If you're driving your car and you put down the sun shade and a 6-inch fat bastard falls in your lap, that's a potentially deadly situations. The mofos are fast too.
Funny enough, huntsman spiders are the leading cause of car crashes up in northern Queensland especially around tourist peak time. As you said you pull down the sun shade and boom lightning fast huge bastard falls on ya, most people are gonna freak the fuck out haha
Grew up in Sydney. What makes funnel web spiders so dangerous is that they are EXTREMELY aggressive. They never run away, always open up and stand their ground or attack.
The search function on TH-cam is the stupidest, most maddening I’ve ever come across. How does a multi billion dollar internet company make such crap? It’s gotta be a reason that benefits TH-cam and not the user.
To defeat your enemy, you must know you're enemy! The global war on arachnids will be won by man.... and earth will be known as home to humanity, NOT to the spiders!
I didn't even feel it when I was bitten by a recluse spider when I was camping in Greece. When I changed my clothes I suddenly noticed that a spot on top of my right hip was swollen and hot to the touch. I looked into the mirror and found the area to be deep purple, almost black. And two little bite marks in the middle. I had no idea what it was, the doctor said it was an infected mosquito bite and gave me antibiotics. Luckily, no necrosis occured. Then the spot faded from the middle to the edge. This typical healing pattern made me realize after some research, that it was a reclusive spider bite. But this is when the aftermath started. Apparently, I had some kind of nerve damage. Sometimes a sharp pain would shoot into my right leg, and two times it was so bad that I lost control over my leg and fell to the floor. The doctors had no idea how to help me. I could walk slowly, and work at my job. But running or working out caused my leg pain to fire up. I couldn't work out like I was used to, and gained weight. It took literally three years for the leg pain to fade away. Now I'm slowly losing the weight again. Damn, that was scary. I still wonder how I was bitten.
My guess is that your clothes probably *are* how you got bitten. While you were out camping, a recluse probably took your clothes for a nice place to hide and when you put them back on, it felt threatened and bit you. Checks with the idea that they like dark places to hide in/under
Not saying this is the right thing to do, but I’m feeling heated at that doctor for not ruling out the worse possibility, or just plain dismissing the more-likely signs. I want to go back and “thank” that doctor with a good kick from my bad leg, and tell them the kick would’ve been much worse since those bullshit mosquito bites were in fact, and obviously, a spider bite! 🤬🦵🏻🥾💥
@@microwoftUsually you see much fancier editing in youtube informational videos. This is straight up powerpoint down to the slides with bullet points. Not that I'n complaining though I'm here for information not flashy editing.
@@sarmeddangerous6462so true. I’m doing pre-med and just finished doing some biology lectures. During the first few minutes of the video I felt like I should have pulled up one note and started typing😂
All spiders are a danger to my mental health regardless of venom potentcy. Except those colorful little jumping spiders that do mating dances. Those can stay.
I have an agreement with all spiders and it's worked well so far, it's either them or me. Includes bugs I mistake for spiders, thats the only hiccup in the whole relationship
I can verify this spider being a cause of car crashes. This indeed happened to my cousin’s wife. Driving, turned a corner, sun in eyes, pulled the sun visor down. Huntsman dropped on her lap. She panicked and hit the rear of a parked bus. As an insect fan, I love big huntsman spiders. Funny enough, despite their size and speed, they are often caught by wasps and hornets. Seen many a wasp dragging a paralysed huntsman to its nest to lay her eggs on it.
@@H41030v3rki110ny0ubut they're cool :( people hate them too much for being angry around autumn when they're just slowly starving to death and taking it out on everyone else, like humans would. I have dealt with many people who just get really angry when hungry and regret any wrongdoing once eaten, wasps just don't have that chance because they're fated to die for winter
Bit by a violin spider when I was a kid in Naples, FL. I have a scar on my right calf and it was a brutal ER episode.

I wonder about that. Are you sure recluse live in Florida? Did you know, over 90% of doctor diagnosed brown recluse bites are actually skin infections? True story. There was a book written in last decade by guy involved in the study. Good easy read. Most everything we "know" about recluse is wrong.
As an Australian I would also like to say that though huntsman spiders are not medically significant, they are still dangerous. One, they smell fear, and I will die on that hill. Two, when you’re driving into the sun and you pull down your sun visor and a hairy, leggy, incredibly fast, dinner plate sized bit of nightmare fuel falls onto your face, lap or steering wheel… you are going to crash. Spiders do not have to be venomous to be dangerous. This should be considered for future videos, because I know huntsman’s have killed. EDIT: I AM AN ARACNOPHOBE AND HAVE SEVERE GENERAL ANXIETY. I know spiders cannot smell fear - that was a joke. And I know they are a reason crashes have happened. Yes, ultimately it was driver error due to an extreme fear response, but in Australia, travelling at speed, blinded by the sun, you aren't going to check if it's a huntsman, wolf spider or funnel Web. You're going to react. Also, more crashes are caused by Kangaroos, cows and wombats than will ever be caused by spiders. I have seen people go off the road and get out their car flailing because of spiders. It does happen. So while the notion might seem bizarre or unfeasable, FEAR, EVEN IF UNDESERVED OR IRRATIONAL, SHOULD NOT BE UNDERESTIMATED.
They are cool spiders, but I thank the heavens everyday I don't live in Australia, because if I ever saw one of those in my house I would probably just kill myself.
I cannot even begin to imagine. I have an irrational fear of spiders that are *HARMLESS* as it is, so if I lived in Australia… I’m probably an idiot for watching this video. Even reading your comment, I’ll probably have nightmares about dinner-plate sized arachnids. Thanks a lot. Lol. 😉
@@sarahrupert5320 If it helps, exposure and education can help with arachnophobia. I am afraid of spiders but decided to get a tarantula as a pet. After caring for it and sleeping in the same room for a year, I have noticed I'm way less afraid of spiders. It's definitely not for everyone but I imagine living in a place with a lot of spiders will reduce someone's fear conciderably
Managing spiders are no joke, I can't believe you didn't talk about them. My cousin Eric was bitten by one and two weeks later he succumbed to management training.
I feel like I'm having a stroke because I don't get what you're saying at all 😂 English is not my first language but I'd say I'm pretty fluent and can understand almost everything.

Got bit by a Brown Recluse when I was living in Salt Lake City, Utah. The necrosis is no joke. Called the University to see what the Arachnid professor had to say, he was in South America for another week. Knowing that venoms are either acidic or alkaline, I decided to pack the wound with baking soda. A week later the professor answered my email and told me to put baking soda on it! Lucky guess by me.
I live near SLC and everything I’ve read online says that we don’t have brown recluses here. Was it 100% a brown recluse? Did you travel anywhere out of state before the bite? Maybe you could’ve brought it back with you in a suitcase. I’m not attacking your story or anything, I’m just genuinely curious. Black widows should be the only medically significant spider that we have here and I don’t think their bites can cause necrosis or even allow necrosis to develop from bacteria. I wonder if we have any spiders here that have venom with the potential to cause necrosis but only if it’s one of those “worst-case” scenario bites like the video was describing. Very interesting either way! Im going to look into it a bit and see what I can find
No, I'm not 100% on that, could have been the Desert Recluse or a Hobo I suppose. Let me tell you when you see your flesh dissolving the size of a dime, you just want it to STOP! Interesting thing is it didn't hurt. It was in our bed, first night the wife got bit on her index finger, second night I got bit on my nipple AND my junk. Needless to say I was a bit freaked out. Baking soda did the trick!
I'm in septic maintenance in Texas, and EVERY SINGLE DAY I see at least one Black Widow, because they LOVE to nest underneath the concrete block the aerator rests under, and I regularly see Brown Recluses in the same areas, though obviously not nesting and not nearly as often. Nothing has made me more careful around these arenas than going to clean an aerator filter, undoing the screw and lifting the plastic cover off the filter to reveal a brown recluse chilling there inches from my fingers, lmfao. Love that they both made the list of the only 4 spiders you ever really need to worry about. ;_;
If it makes you feel any better, there are really two tiers within the four horsemen, with recluses and widows tending to be less dangerous, their venom more likely to make you somewhat sick and in pain than threaten your life, than wanderers and funnel-webs which can be aggressive and often send you racing to the ER if they bite.
There hasn't been a verified death from a black widow in the US since 1983. Turns out they are way less deadly when doctors don't load everyone up with opium and whiskey lol.
@@Huuuuuuue Yes, you die from wanderer and funnel-webs mostly because you are far enough in the woods or because it works its way up your body and shuts down all your nervous system and all your muscles, You basically end up dying from the venom getting close to the heart and your body not knowing what to do about that. Once you introduce steroids (ER steroids that is) and lorazepam (Ativan) or diazepam (Valium) to help the cramping stop. I don't know what they give for Wanderers and Funnel webs. Those two in particular are aggressive and I mean their venom is also aggressive. You could find yourself dead in under 10 hours.
@@Huuuuuuuedid a study on funnel webs a while back that venom is no joke hyper aggressive almost all female so even more dangerous and are really smart leaving carcasses of smaller prey at the top of their funnel and chilling outside of it when something goes for it it dives into it sealing the funnel with webs and quickly taking down birds and rats that go for the carcasses
I turn up a lot of spiders during remodels. I don't want to step on them so I usually guide them gently onto a hand and take them somewhere safe. I realized after years of doing this that I had been misidentifying the brown recluses. I had thought they were a small spider, but then I discovered they were as big as the common house spiders, and I had probably handled a dozen of them with my bare hands, unknowingly. The trick is to not grab at them; you put down a hand and let it become terrain while you guide the spider onto it.
@@sndspderbytes mentioning no names But with the Other genus of funnel web starting with H don’t know the proper spelling but I heard from a funnel web collector and dwa licence holder he said there was a certain sp of said genus to have venom 2 to 3 times stronger than the Sydney funnel web. But with the six eyed sand spider I hear it is likely to be seeing said spider on a dwa list some time in the future. If it isn’t already. Bearing in mind I heard this 3 or 4 year ago.
When I was younger I had a spider I'd never seen before come near me, the part that stayed with me was the fact it has such a similar pattern to a "redback" spider or a widow but was pure white. I've never seen a spider like it since, it was both beautiful and terrifying.
I hope this channel blows up, it's so clear, thorough, and informative. Seriously underrated videos you got here, more educational content should be like this. Really looking forward to the next one!!
New Zealander here, while we technically have spiders of the widow family (namely the katipo), the widow spiders we have here are harmless to humans, to the degree that we don't even issue anti venom unless you have an allergic reaction. No deadly spiders in Nz and I love that fact aha
The bites from black widows and recluses usually tend to be uncomfortable and cause sickness, but are not usually deadly, really the only 2 that are a genuine threat to your life are the funnel webs and wandering spiders. Definitely though black widows and brown recluses can be considered dangerous, but not quite on the same level as the other two. Great video, I assumed it'd be clickbait at the start like the vast majority of 'dangerous spiders' lists as you showed, but this was very informative :)
Recluses may not be likely to kill anyone themselves, but without medical attention, the infections you will almost certainly get in areas affected by necrosis very well could. Before the discovery of Penicillin in 1928 they were much MUCH more of a threat.
“Uncomfortable” is putting it lightly. The pain is off the scale. Incomparable to almost any other insect bite on the planet. No, they won’t kill most adults, but their bite is incredibly painful.
I love getting recommended small channels and just finding genuine quality content. I don't even like spiders but damn this was interesting and you narrated the video really well. Have my subscription :)
I moved to Australia 15 years ago and was terrified with all the spiders i was suddenly surrounded by and i believed all the random "facts" about how venomous some of them were. Like daddy-long legs being the most venomous, but its fangs being too small to bite humans and white-tail spiders having necrotic venom. I understand them so much more now and am very familiar and fascinated by them and now im the guy people call if there is a big spider that needs to be taken outside safely. Most of the truly dangerous spiders here can be fairly easily identified and avoided. Funnel webs are pretty easy to ignore as long as you dont get too many of them in one spot and around children. Red-backs are always found in garages or sheds so its always smart to wear gloves when moving furniture or stuff that hasnt been moved for a while. Brown recluse/violin spiders are more common in Queensland but seeing them is fairly rare but i met someone who insisted that their spider bite that necrotised a part of their legs was a white-tail and i couldnt convince them that it was probably a recluse. Basically, if you get bit by a spider here, its a very, very good idea to catch the spider that bit you and bring it with you to the hospital if you have any severe symptoms so a professional can identify them
What's funny is people still believe that granddaddy long legs are the most venomous but what's funny is they've extract the venom from them and the venom is not even potent enough to kill small insects😂
As much as I love snakes, I'd be much more worried about accidently stepping on/near a brown snake than any of the spiders lol. But even that is pretty easily avoided.

I agree to an extent. Just don't get bit again trying to catch it. The first bite may have been a dry bite, the second could be a full envenomation and put you in real danger that you weren't in yet. Even deadly bites are rarely deadly in western world with access to hospitals. Most deadly envenomations are not deadly in a modern hospital. Your life does not depend on catching the offender. It can help, but isn't likely to change your outcome. So don't go overboard trying to catch it. More important is getting proper medical treatment before major symptoms appear. If you have systemic effects a hospital will save you whether you have spider or not. Now if you are in the desert 190 miles from the closest doctor, that brown recluse bite just got a little more serious.
Thank you algorithm. It'd be interesting to see a similar video about scorpions. I feel like they're often overlooked.

Arachnophobia- irrational fear of spiders. I have it, but by learning about spiders, enjoying your video, understanding their purpose and behaviour i have learned to appreciate spiders. Your presentation is one of the best videos I've seen on youtube - great work, nicely done and well worth watching.
Good for you! Keep going, and you can absolutely beat your fear through curiosity and exposure therapy. I did it and it was one of the best things I’ve ever done for myself, not only for the thing itself but because it taught me that I can overcome any fear I have, and my thoughts are not reality. Keep up the amazing work! 😊
Great video, man! I think you did a really good job. A couple of points: - Another reason the Atracidae males are so defensive is because they are very clumsy outside their burrows, they’re completely outside their element - It’s a very small point, and it is accurate to refer to the tagmata of spiders as the cephalothorax and abdomen, but I think there’s a strong case for using the term “prosoma” over “cephalothorax.” “Cephalothorax” means “fused head and thorax,” but there is neither fossil nor embryonic evidence that spiders have ever had separate heads and thoraxes. “Prosoma” is also easier to say, as a plus - I understand that you plan to release a follow-up video covering the actual danger posed to humans by these spiders and don’t want to steal that video’s thunder, but I would have liked it if you would have mentioned that the majority of Loxosceles bites do not produce necrosis at all, let alone more significant effects, and that deaths by Latrodectus are exceedingly rare. People are exceedingly impressionable, and when you have an audience like this I think a certain responsibility exists to do what you can to mitigate the damage that has been done by fake news. Granted, I do think this video overall does a good job of living up to that responsibility by showing how very few spiders are potentially dangerous, and I have to thank you for that!
Thank you, I do prefer the use of prosoma and opisthosoma, as there is legitimate reason to not use the term cephalothorax or abdomen. I just don't want to cause extra confusion for any newer spider enthusiasts who may already be familiar with the latter two and don't want to be swamped with terminology. I made a sacrifice splitting this video in two, for sure. Part of me still wonders if it would have been better to release a 45-minute video and just have all the information in one place.
I can only think of two, the Sydney funnel web and the black widow. The six eyed sand spider is debatable if that's on the list and I just can't think of a 4th other than something like a brown recluse that can cause allergic reactions or other issues caused by swelling.
@@georgehenan853 I've been bitten twice by brown recluses when I was a kid, both times on the foot when I went to go to the bathroom late at night. Where I live in Kentucky they are everywhere. I see them almost every day. But thankfully I just had some swelling the first time and nothing the second, maybe a dry bite so that's why I was thinking maybe it was more allergen related.
No one has ever died from a Violin spider bite, & there are only 3 recorded deaths, worldwide attributed to Widow bites. So 2 of the spiders on his list are NOT deadly.
Legit one of the best educational videos on spiders I've ever seen, ppl always mystify this stuff so much but you turned it into a simple step by step process. I'd usually go by habitat but apparently I already had most of those types in my head as dangerous. Widows, recluses, tunnel webs, but I always forget the wandering spiders. Also pfffft, "wolf spider bites" those things' venom feels like a bruise at absolute worst.
I love wolf spiders and let them live in my house unharmed. They take care of the bugs that “bug” me. Fiddlebacks on the other hand are kill on sight. Black Widows are usually always outside, so I leave them be. Thanks, great informational video.
@@mattihaapoja8203 No you don’t see them often, they’re to shy and don’t walk around like other spiders. If I looked around the outside of the house I might find one but not necessarily a large one. It’s really not a problem living near them or any other spider/snake, certainly not something I worry about, the way they portray Australia is overly dramatic
@@mattihaapoja8203 it depends on where you live. I will see anywhere from 10 to maybe twenty a year. We have to check our shoes constantly. The funnel are no joke and you definitely wouldn’t want to get complacent
A couple of tarantulas have medically significant venom...Poecilotheria regalis and Poecilotheria metallica. While not capable of causing death, unless the victim has an allergy or underlying health issues, both can cause systemic effects in humans. I had a P. regalis about 30 yrs ago. Wicked fast and moody. I also have a Brazilian Wandering Spider preserved in formalin. It was super aggressive. It came in with a banana shipment to a local Phx grocery store. I always tell people in stores to watch where they grab when getting bananas. They look at me like I'm stupid. Nice video.
Thank you, yes. I thought about including Poecilotheria in here. A few experts do regard them as medically significant, and they're certainly more dangerous than the new world tarantulas, but I chose to focus on just the spiders have threatened and taken human lives before. It keeps things a lot simpler. Those tarantulas are beautiful, by the way.
There are actually a few more than just those two for example Togo starburst baboon and many more the Togo I can vouch for not fun

No arachnid is aggressive towards humans. They can be defensive. They can be aggressively defensive. Just ask anyone with an Obt or Orange bitey thing. But none of them are aggressive to non prey animals. If they waste their venom on us, they may not have it when they get attacked by predator or find a tasty meal. It takes a long time and a lot of energy to make, so they really only use it defensively. If they are being "agressive," they are scared and hoping their erratic behavior will make you leave them alone. That is the goal of aggressive arachnid behavior. Sometimes they are just trying to find a hole to hide in too. That's why Solfugids or Camel Spiders (not spiders, or camels) run "at you." They are running at your shade hoping to find a place to hide. But people anthromorphizing them see it as aggression.

My dad worked in groceries in 70's and still talks about the spiders in the bananas. Now I'm wondering which ones he was finding and wish he would have started breeding colonies. When I tell him that he looks at me like I'm an alien. I don't understand how arachnids don't bring joy to everyone. They are so fascinating.
That will be your little secret. After more than 50 years of being a spider fanatic, I can say with confidence that OBT's, which I have owned, along with about 3 dozen other tarantula species, is indeed aggressive towards humans, as are brazilian wandering spiders. Solifugids, not so much. They're just looking for shade. True, most are simply being defensive and showing a threat display. Yes, I know about wasting venom. You're not the only one here that knows arachnids.
Absolutely amazing video! I’m a huge spider nerd and have kept many species. This video is so concise and informative. Also, it’s very detailed! Seriously amazing!!
I always found it so fascinating how such tiny miniscule animals like spiders and scorpions evolved Venom so potent that it can kill a horse/human. It's understandable with snakes, given they're dead in the center of the food chain and deal with everything from cats and hawks to wolves and mountain lions, but spiders really only have birds and small mammals at the absolute worst.
Ain't no kill like overkill, eh? You see similar in some plants, too. They generally only have to worry about bugs, but some of them go crazy in their defenses.
A big part of it is that the spider bite itself doesn't do much physical damage, whereas on snakes they have big fangs to transfer the venom which will go deep into the small-medium mammal's body and could be directly injected into the area their venom will do the most damage. (muscle toxin, tissue toxin, targets organ function etc.) Spider venom almost always enters through the surface-level bloodstream not directly into muscles or tissue or organs. Evolutionarily this means that spiders have had more time to perfect venoms because the way in which the venom is applied remains constant. In snakes, since the venom is applied directly in the zone where it works (on prey not on human bites) and since the bite itself is like being stabbed as well as being poisoned, their venom doesn't need to be quite as potent to be just as effective.
@zehkiel8018 Some plants! Parsley has about seven deadly lookalikes on its own, even wild carrots are poisonous in many cases. its ironic because mushroom hunting is so demonised, but plant foragers are actually far more at risk
It's always great to see another creator in the space give their takes on arachnology but the Widow and Recluse really aren't that lethal at all, except in small children and the elderly, and are mostly just painful. They also have a tendency to dry bite as well, so your chances of being envenomated are also very low. Sydney Funnel Weavers and Brazilian Wandering Spiders are definitely no joke though. Overall doin great, just wanna help keep your information accurate to better serve the audience :)
Yup! That tends to be true of most spiders, regarding the age range. The most serious case of a mouse spider envenomation was on a small child, the "record breaking" 15-minute kill from a funnel-web bite also involved a young child, and Phoneutria Wandering spiders seem to be incapable of killing anyone over 7 and below 70 years of age according to the medical stats.
the biggest issue ive ran into with recluses and widows is that they are pretty easy to accidentally disturb. speaking from experience in texas, the recluses LOVE hiding in drawers or cupboards. this combined with the necrosis risk provides a big threat to many underdeveloped communities. wood piles or trash heaps have to be flipped a few times before you can even go near them
@@lucasvinson982Yeah we get recluses and widows in my area, and the recluses are everywhere, they come inside too. Luckily I've never been bitten so far! The widows stay away from people, and it's pretty obvious if you touch one of their webs (vs another cobweb spider) since their webs are harder to break.
@@arachnorion my dad and uncle used to catch sydney funnel webs and send them in for milking. One day they were collecting spiders and my uncle was bitten. Grandma was furious but he was saved using the anti venom that he had collected. I also pulled one out of my dogs mouth... My dog was unfazed and I was disgusted
Recluses may not be likely to kill anyone themselves, but without medical attention, the infections you will almost certainly get in areas affected by necrosis very well could.
I live in the hotbed of brown recluse spiders in the US, they have this horrible rep as super dangerous but at the same time those of us who live around them know they are some of the laziest, non-aggressive spiders that exist, unless one gets into your clothes you pretty much will never get bitten, they're a totally chill to the point of being boring, I literally see them every day and I've been bitten once in my 50 years and that was when I was young and was crawling around in a crawlspace below a house, I crawled through at least 100 of them and one took the time to bother biting me, and if you get bit the odds of it becoming bad is quite low
First thought as an Australian was "redbacks and funnel webs", but having a neurological disorder, the way you described the effects of neurons misfiring and causing pain in places it shouldn't was better and more concise than my neurologist.
I really like this style of video, feels like I took a course. The way you presented this was really like I was being taught the information rather than being told it. I love learning about spiders, glad to have discovered your channel man
This was one of the most helpful, informative, and truly scientific videos I’ve found on TH-cam. Absolutely amazing. Going into detail the different venom classifications and how they deteriorate or rearrange cells was an extremely intriguing. I had taken chem 2 in college and remember going over how a scorpion stings venom works on the cells. Truly crazy how it works on a cellular level.
An excellent video with some fine deductions! I am going to say the White-tail more properly belongs in group 3. Science and the medical profession tends to dismiss the harmfulness of these for good reasons. This may be disputed by those that have suffered negative effects and the usual response Is misidentification. However, I used to live in New Zealand where these are now far more prolific than in their native Australia, where I now live. Probably due to lack of predation. I have seen about 10 in the 13 years I’ve lived in Western Australia, whereas it was not unusual to see that many in a day in Northland, NZ. It’s hard to imagine anything else being misidentified as a White-tail in NZ. These would quickly establish themselves in the new houses we were building at the early framing stage in significant numbers. I witnessed a colleague sustain creeping ulcers from a verified bite on the outer thumb that gradually moved up his arm in several places below the elbow. There are also plenty of anecdotal cases of this happening. A physician in the South Island took this seriously enough to be concerned for his elderly patients. Although some of this ulceration may be attributed to the effects of diabetes in the elderly, there are enough instances of healthy people being affected to indicate something else may be going on. There may be other mechanisms at work as the venom toxicity has been shown to be mild. But I know what I saw. I am also finally healing from an ulcerated bite on my lower leg that appeared after gardening about 3 months ago. This resisted topical and oral antibiotics for weeks, but was almost immediately on the mend after applying active Manuka honey MGO400+. I didn’t feel the bite and remain reluctant to blame anything in particular. As for the Sicariidae, I worked in Namibia for a few years. These spiders lived in places where interactions with humans were practically non-existent. But I believe there was one recorded case of a bite which led to fatal medical consequences for the affected person. The report listed necrosis leading to amputation of an arm and subsequent systemic organ failures. This report seems to have disappeared in the 15 or so years since I encountered reference to it. My interest then was driven by a very real desire to acquaint myself with hazardous wildlife in a region I was going to be spending much time in. In reality, the real threats were the very large and venomous Parabuthus scorpions and other flavours that were everywhere, snakes such as the Rinkhals, and the Baboons. Not to mention some of the more criminally inclined and well armed locals.
I love this video. The fact that it talks about the actual component of the venom indicates how trustworthy this channel is. And the use of scientific research makes it even better. Its not just someone bored oppening Wikipedia (nothing personal Wikipedia is great but using just Wikipedia is very bad for researching). Keep it up
The fact that funnelweb venom seems to specifically target primates is particularly bizarre because Australia had no native primates before humans arrived.
Good stuff!! To my view, dangerous spiders arent just the ones that could hurt me, but that, for example, could hurt my dog. Perhaps some venoms arent a thread towards adult humans, but are for kids. It would be great to know more on that if sometime you need an idea for a video! I liked this one a lot
Ethics will prevent such information from being found out. If a child dies to a spider bite that wouldnt kill a adult it will be attributed to something else unless through some miracle the kid gets bit, captures(not smushes) the spider and the parents dont throw it out before the child dies (because if the child survives it will be considered a sudden flu or food poisoning from eating too much dirt or the like) and on top of all that the parents bring the spider to a spider expert and on top of that the spider expert would need to believe the word of a (deceased) child over his own ;about spiders of all things; to even consider it as a possibility and maybe start testing the hypothesis. TLDR: the info doesnt and probably will never exist about such a specific thing.
My arachniphobia is so severe i was having awful anxiety even just looking at the photos of spiders you put up.. but i stuck through with it because this was an interesting video and i very greatly enjoy the college style presentation youve done! Also, I live in Oklahoma now and lets just say i didnt have to deal with nearly as many spiders when I lived in Alaska 😅
I have heard “banana spider” refer to 3 kinds of spider: the wandering spider (deadly), the yellow sac spider (annoying but ultimately harmless bites), and the golden orb weaver (probably the biggest non-tarantula in the USA, beautiful, enormous, idk anything about the bit but they were not mentioned in the video). Most of this is local dialect and varies by the region, so if I’m in Texas, it’s probably the Golden orb weaver; if I’m in the Midwest, it’s probably a yellow sac spider; otherwise it’s a toss-up because most people I meet don’t know one spider from the next and I can’t pin down a certain region that calls the wandering spiders banana spiders. Also glad to see that jumping spiders are not mentioned here because they are cute, friendly, and harmless.
This was a great and informative video! It’s always great to see someone present honest information about these animals, they have been subject to misinformation and sensationalism far too long. I would also like to add that fatalities from Loxosceles reclusa (the brown recluse) specifically, as well as Latrodectus as a whole, are vanishingly rare, and only prove deadly in a tiny minority of bites. Additionally, funnel webs have not caused any fatalities in over forty years, and with treatment, the survival rate is 100%. Even before such treatment was invented it was more likely than not to survive a bite from an Atracid. In the case of Phoneutria, they rarely even cause severe symptoms to begin with, with the vast majority of bites not causing the crazy symptoms associated with this spider. Also, the first image you used for Phoneutria is actually not a Phoneutria at all, instead being a spider in the genus Cupiennius, which are harmless and more closely related to fishing spiders than wandering spiders in the family Ctenidae. Finally, it is incredibly easy to not be bitten by any of these spiders. There are simple precautions that can be taken to avoid negative interactions with these animals, and for the most part, they do not pose a significant threat to human beings. Overall, this was a great video! I just wanted to say a few things :)
Hey, thanks so, much. I will absolutely add that correction somewhere regarding the Ctenidae spider that wasn't Phoneutria. Thanks for catching that. All of those points you made regarding venom were originally in this video but got cut because I couldn't get the run time low enough. That's why there's a part 2 coming really soon. Edit: Cupiennius isn't Ctenidae. I stand corrected. The eye pattern threw me off here. Can I ask how you identified that specimen, so I can use similar techniques in the future?
@@arachnorion Alright sweet! Although the Cupiennius are in the family Trechaleidae, though I’m pretty sure they were originally thought to be in Ctenidae, they do look rather similar! Anyways, I loved this video thoroughly, I have subscribed and will patiently await the second part :)
@@arachnorionAlso I just noticed your edit! Well I mainly identified this specimen simply from the coloration, as I recognize Cupiennius coccineus, but generally the best way to tell them apart from Phoneutria is to take a look at their chelicerae, which have vertical stripes going down them. Phoneutria usually don’t have these! I’m not entirely confident it works with every species of both genus as I don’t know every single species in both genera, but at the very least the most recognizable ones can be identified easily going off of this rule of thumb! Hope this helps, and I apologize for not seeing the edit before :)
I really like the way this video is set up like a lecture w slides. It was a lot more digestible to me bc of the format helping remind my brain this is for learning not entertainment w my ADD and excessive background content watching. Just helped me focus a lot fr
I got bit by a fiddle back and the necrosis from it was exactly like you described and it’s been hard to find proper information on what happened or why it happened. I appreciated this video greatly!
For those who don't already know, the brown widow is harmless and helpful. I used to work in an overgrown greenhouse that was swarming with them. I must have been bitten by them many times but it's not like I could tell those bites from the mosquitos and ant stings.
Science wasn't really interested in the brown widow, so information slowly dripped out over many, many years, hard to keep up with, hard to fully understand, plain, and simple, not enough drama??? It's like the servil in Africa. Why talk about the Serval when you can talk about lions, leopards, and cheetahs. I definitely appreciate your first-hand knowledge!! I didn't realize the Servil existed for many years. The wild dog was much easier because they traveled in large packs. Making them more capable of killing large prey!!

They are venomous too. Though considered to have milder venom, and are unlikely to bite like the others, they still have venom and should be treated as such. Which to me means pick them up and talk to them. But you do you.
To start a compliment: Good presentation. enjoyed this even though I do have a few corrections for you spider 1: Latrodectus - there have been no confirmed fatalities since the start of accurate recording in the 70's. the closest to come to that is the red widow (Latrodectus bishopi) who's neuro-toxin venom can latch onto nerve clusters and give recuring symptoms for the rest of the victims (otherwise long and healthy) life. This misconception of the lethality of black widows is thought to have come from the treatment that was historically used. the treatment would be to dose the victim with laudanum, in some cases this would be given in such a high dose that the victim died of overdose, not the spider bite. Spider 4: Loxosceles - Again not a single confirmed death has occurred from these ever, not even from laudanum treatments. they are unpleasant and absolutely medically significant, but not fatal. As an aditional, I have been bitten by a steatoda nobilis, it was not pleasant. a weekend long migraine combined with severe contractions to my neck and back muscles to the point that the hospital thought I had contracted meningitis. Lumber puncture confirmed it was not and I later found the spider that bit me. She ended up having a very impressive web in my window and I was mindful of her (and even gave her a few pest insects as food. she would give this funny little butt wiggle when lining up to strike the prey) and there were no other bites. I named her Veuda. Though she died of natural causes one of her offspring (also a female I have named Solara) now lives in a different window and continues to keep my home pest free.
Thanks for your comment! I love when people share stories of their symptoms after bites. It makes the event a lot more personal. As for your corrections, part of what makes gathering bite data difficult is judging what qualifies as confirmed bite cases. I think there are a couple of inconsistencies in what you're presenting. For example, the study I'm linking below reviewed over 20,000 Loxosceles bites in one state of Brazil over a 7-year period and counted 7 deaths. The fact you say there are zero deaths ever makes me think your standards of what you consider a "confirmed bite" are very high. This is fine, but by the same standards, your own S.nobilis bite would be suspect of credibility, and I would argue no one has ever died from a Phoneutria bite either. You mentioned L.bishopi as the widow that comes the closest to having fatal venom, but this seems inconsistent with your other comments. What are you using to judge the spider's venom? Is it the report on J.Hollenbeck's notes after he reportedly sustained a bite? Because this would not qualify as a confirmed case under the previous standards, and if this is where we're moving the goalpost, I would then argue TONS of people have died from Loxosceles and Latrodectus bites. I'll link a case from a medical journal down below as an example. Zero people ever having died from Loxosceles bites might be correct is we exclude certain data. Several people having died from Loxosceles bites is also correct if we choose to include certain data. What's important to me is that we stay consistent across all spiders when choose which studies to cite. I'll probably make another venom video in the near future. I'm loving how many well-read individuals are showing up to comment, and the interesting points being made. www.scielo.br/j/jvatitd/a/LyKGHVrm6ktHhrCbyxtwdxz/?lang=en www.annemergmed.com/article/S0196-0644(03)70140-1/fulltext
@@arachnorion Agreed citing sources is very important. I'm going on the CDC records for the 'death count' of both widows and recluse. As for the red widow, there is little official data, granted, however what little there is does corroborate my statement on the effects as well as patient testimony. Both false and true widow species have been getting a real bad wrap in recent years when the numbers just do not bare out the hype. Nobilis are wonderful houseguests and will largly stick to their webs and will even retreat to their 'burrows' (or in a house it might be better to call it a hidey-hole) when they see a human looking at them. A reaction both documented and personally observed. I was surprised that you didn't mention the European tube web spider (Segestria florentina) I remember a few years back these were often being mistaken for funnel web spiders. I hear their bite is fairly potant but not considered medically significant. (thinking a 2 on your chart). I personally think they are beautiful with their glossy black head and the brilliant green stripe on their pedipalps. Personally only encountered one in the wild, but was not disappointed. (personal note: Solara earned her keep last night and got rid of an annoying house fly just before I dealt with it myself. Gotta love those really strong trap lines they make)
Thing is, going off of "confirmed deaths" or "bite to lethality ratio" is misleading to rate their true lethality. Fact is most spider bites are irrelevant because they don't often inject enough venom before escaping due to being such small creatures that would rather get away from the threat. Often they will dry bite and inject no venom at all. We are not their prey. They only bite quickly out of fear and do not stick around to ensure a fatality, as that prolongs the encounter and puts them in danger. However, if you look at their actual venom potentials rather than bite records, you'll see that they are very lethal. Academia concludes even the widows, among the weakest of the four, as 15 times more potent than a rattlesnake's venom drop for drop. Problem being they are so tiny compared to a rattlesnake that it doesn't really matter. But that is a staggering effectiveness. So its not like calling them extremely deadly is misleading at all. When a creature can kill up to exaggeration 120 septillion rats to the power of 10 with a single drop in a laboratory setting, its safe to say they are deadly, regardless of how ineffectual their bites often are when applied in real world, because their priority is to escape you, not to waste their precious venom on non prey. It would take a special set of circumstances for dangerous bites to occur - if spiders are trapped by pressure between a surface and a body part only then does it become dangerous as they have no other choice than to give a sustained bite to the fullest measure. Instances like this are rare and only when someone is leaning on one or they are trapped in a shoe
@@DiamondxStyles By your set of data then apples should be banned as they contain cyanide or onions as they contain produce aspirated sulphuric acid where as if we ask "How many people die per year from the toxins in apples" you find the answer is.... none. this exact type of science led to the tomato being banned in the 1700s as they are in the same family as belladonna. it is MUCH more factual to look at the very real numbers from the real world asking questions like "how many bites from species x directly lead to death". If the black widow is a lethal species then how are the presenters of 'kings of pain' still alive after forcing a bite? Feel free to find the video and witness it for yourself. I'm not saying that the venom isn't lethal in sufficient quantity, but that isn't the question we are answering. The question we are answering is "is the spider's bite able to kill a healthy human?". So far I'm only aware of 2 species where the answer to this is yes. Rather than looking at what if, we need to look at what is. To put an amusing and extreme example on this from a real world example: Shipping crates of bananas has set of port authority alarms for nuclear weapons as they are radioactive, however, this level of radiation is not harmful in the dose people are exposed to it in. it takes a shipping container amount to even become registered. that is more than a person can eat in their entire lifetime!
Thank you so much for your in-depth knowledge Abt this arachnids. I recently came across a very large black spider and due to fear I had to relocate to another place for the night. I really don't know what type it was but it was just too large. I truly enjoyed your highly educative videos. Thank you.
Good video. I have a couple of comments though: 1) 12:30 is Cupiennius getazi, not Phoneutria sp. 2) 26:49 it is worth noting that this is outdated literature. The abstract refers to both New-World and African Sicarius sp. This genus has now been split into New-world Sicarius and African Hexophthalma. The relative toxicity of the SIcarridae family (Sicarius, Hexophthalma, and Loxosceles) is quite contentious, with some studies (including the one you showed) suggesting that Sicarius venom exhibits lower levels or no SMase D activity compared to Hexophthalma and Loxosceles, but other studies indicating that there is comparable activity but the molecular mechanism of action may be different. Further work is needed, but it seems currently that there is a non-negligible difference in toxicity of the venom within members of this family. I actually own a couple of Cupiennius sp. and a Sicarius thomisoides. The latter is about 2ft from my face as I type this!
Thanks for the reply! I'm super late when it comes to posting my research sources for this video, but I intend to add a note about that Cupiennius spider. Someone had mentioned it before and I was unable to link it to one of the (is it 9?) Phonuetria species, leaving me to believe it was indeed Cupiennius. Thank you for also mentioning it. In many of my previous recording attempts, I had mentioned that African Sicarius spiders had been reorganized into Hexopthalma, but in the end I decided against mentioning it, since it had little to do with the point I was making (phospholipase D is found in every genus of Sicariidae), and I didn't want to confuse people by throwing out every fact on these spiders all at once. At least Ornatus is still in Sicarius, so the main point of the paper is consistent with the current nomenclature.
@@arachnorion Hi, no worries! Glad I could help, if only a minuscule amount. Perhaps I am too close to the subject, but I think the genus split is relevant to the point you are trying to make, since you are discussing relative venom toxicity, which seems to be variable between the two genera. The same group which published the 2013 paper you presented also published one in 2021 which argues that there is evidence for a differing mechanism of action between SMase D in the genus, which may explain some interesting observations in their activity. I understand why you didn't do a deep dive here, but I think conflating the two genera when talking about toxicity is missing some key detail. But either way, a great video and one I think is important. Spiders get a hard time considering their relatively low venom toxicity compared to snakes and some species of scorpion.
I've been bitten by a brown recluse before, it was on my lower abdominal area about 5 inches to the right of my bellybutton. I didn't realize that I had even been bitten (more than likely whilst I was asleep) until a day later because I started feeling a sharp pain and noticed that the bite area had GREATLY swelled up (and I mean BIG TIME SWELLING) then when the necrosis set in after the swelling had greatly gone down it LITERALLY looked like someone had shot me at point blank range with a .45. I LITERALLY had a hole on/in my stomach slightly larger than the size of a quarter and I could fit at most about half of my finger in it (I know this for sure because I treated and cleaned the wound twice a day using peroxide and neosporin, couldn't afford to go to the doctor/hospital, and I'm a 6'4 man with some BIG hands). The pain from the bite itself had faded away but if I bumped into anything or got poked blah-blah-blah HOLY $HIT it was one of THE WORST pains I had ever felt in my entire life!! It took me about 3ish weeks, if I remember correctly, to make a full recovery as far as the literal hole in/on my gut goes and surprisingly I didn't experience any vomiting but did have the chills with slight fevers here and there.
In South Carolina, we do have lots of funnel spiders, they just aren't these big, onyx-looking ones. Ours are thin, brown and ungodly fast. They get pretty big and some of them literally can move out and in of their funnel so fast that you can't even react. I don't think they're very deadly, but either they kill losts of other large spiders or they'll shed in some way, because you'll see at least 1 old spider husk in each of the larger ones webs. They always make them against something, so it looks like the swirl of a drain sucking water down into a little hole against your house or woodpile, but - there was one noteworthy year -- a long time ago -- where they must've had some freakish population boom and you'd see their webs randomly strewn about all over the woods every morning, when they were all covered in dew --- like a bunch of miniture tornados. We also have these big bodied yellow spiders that live near swamps and marshes that people call bannana spiders, but they definitely aren't the kind in australia, because they make massive webs up very high and aren't that huge, although they can easily get as big as your hand.
This video was great man but if i can give lne small recommendation try adding stock footage of the spiders youre talking about doing various stuff or just different images as youre talking, such as the size difference between male and female latrodectus or paraxial fangs next to diaxial fangs
I have a cousin that's a few months younger than me and she was bitten by a violin spider at a very young age. She ended up getting a MRSA from it. Luckily she survived, but it was scary seeing her so sick from a spider bite.
I work at a summer camp in Mississippi called Twin Lakes, and like a lot of places, we have had sightings of fiddlebacks and widows. Since camp is a place with a lot of younger people (i.e children ages 5-15), it can be sometimes kinda dangerous to do activities such as horseback riding and ropes due to the really high population of these spiders. I know that they are not out there to hurt humans and with good supervision can be avoided and left alone, but there’s always the chance that a rather adventurous child goes off and gets bitten by a “pretty black spider” that he/she decided to mess with. I work the horses activity and I once saw four black widows together on a fence on our riding ring. I had not only never seen them up close before, but also not in that multitude!
I have been bitten by a Red Back by accidently put my hand in her web. All it did was to make my finger swell and get stiff for about a week. I was bitten by an Australian trapdoor earlier this year. I reacted badly and the bite area went black and it was like a surver burn. I got sick and had a recurring rash on my leg for around 3 months. I was treated with antihistamine steroid course as my doctor thought it was a allergy to the bite. I have a deep respect for all poisonous spiders, especially after this year.
My husband used to be an installation tech for Dish, so he’d have to go inside of houses to check out connections and stuff. There was one particular house he went to in Detroit; run down, but the owner had a really nice TV. Hubby went into the basement and in one spot, he thank God looked up before it was too late because there was a brown recluse in a web, plus egg sacs that had hatched. He immediately called his boss to explain what was going on, ‘cause hell no, he wasn’t risking anything. He let the home owner know he had a brown recluse infestation, which he needed to take care of, and that he couldn’t do the job. He dipped. That story is embedded in my brain.
I had 3 separate hatches of violin spiders under the front stairs. within a week the front stairs were turned into solid concrete. they are still around here and there but not in the hundreds anymore and the few that DO get inside are eaten by the cellar spiders which works out wonderfully. nature has so many ways of balancing itself out it is kinda crazy.
Saw "The Four Killer Spiders" and thought this was a band, clicked thinking I'd hear an album I've never heard before. Instead, I found thirty three minutes of phobia reminders. Lol, oh well still watched it.
This video immediately grabbed my intention as a spider enthusiast and compelled me to click on it and not ignore as poorly researched fear mongering clickbait. The thumbnail focus on eye patterns told me before even watching, that you know what you are talking about. Liked for the algorithm to spread this around instead of clickbait top 10 content farms
Nice to see a well researched and factual video for a change. For killer 4 though, rather than using the genus Loxosceles, I'd have used family Sicariidae, which Loxosceles spiders are part of instead as the African six eyed sand spider (Hexopthalma hahni) is said to be the most dangerous spider on earth. In spite of this great video
I strongly considered it! The reason I left it out was for consistency. People tend to overhype the danger of some of these spiders when the data doesn't support it. It felt wrong to point this out, only to then cite a case of a spider with 2 or 3 suspected bites and no confirmed ones. I legitimately believe Hexophthalma and Sicarius might surpass other spiders on this list in terms of venom potency against humans, I just don't have the evidence to swear by that idea just yet.
@@arachnorion I can absolutely see your point here. The fact that there is very little data in regards to the threat Sicarius and Hexopthalma pose, it was probably the right decision to make. Loved how you used Atracidae as a family for the Aussie Funnel Webs as most would've cited Atrax robustus on its own, where there are 6 Atracids which have caused severe life threatening envenomation symptoms in bite cases so I tip my hat to you on that. You've got my sub for sure man as your video was factual and on point compared to the thousands of videos out there that are pure sensationalised misinformation. Keep up the good work dude.
I'm a little skeptical that it's the most dangerous in the world. They are a species of recluse, so I've read, and also that there are no proven cases of humans being bitten and apparently only 2 horror stories about them weren't confirmed bites. This was on research I did from other spider experts. Not saying they aren't dangerous but most dangerous in the world is a stretch, eapecially since it was never recognized by Guiness like the wandering spider and Sydney funnel web were.
Black widows also love cardboard and barrels that are turned upside down Ive found dozens of them over the years where I work. They are certainly frightening looking spiders! 😬😳😖 Also my sister was bitten by a fiddle back spider years ago and had a lot of trouble with it the doctor couldn't get it to stop breaking down her leg where she got bitten and even now she has a crater where it was at that is pretty deep and really darker than the surrounding skin. 🤢😬🤷🏻♂️
The lesson from this is leave spiders alone, and they will leave you alone

You are right. But it is an over simplification. Most people's last thought is picking up spiders. A majority of bites are from accidental contact. I got a black widow dry bite in Moab one night looking for Scorpions. It had a web across a part of trail narrowed by large boulders. I triggered it and got tagged in shin. After contacting a toxicologist I know in Europe that was awake I waited by trailhead for effects of venom. Was told after 5 hours of no symptoms I could consider it a dry bite. It was thankfully. I hold them fairly regularly and have never been bit. Go on a hike at night, and boom. Sometimes it's hard to keep your distance or even know they are there.
Not always true. Once I opened a closet I rarely used, and there was a huge, brightly colored garden spider, with a web that covered about the whole doorway. I said, "nope," shut the door, and forgot about it. About a week later, as I'm dozing off for the night, I get a stabbing pain in my butt. I slap whatever it is, get up, turn on the light.. it was that damn spider. It had left its web and gone hunting for animal blood in the night. Nothing I've seen written/spoken about garden spiders has ever mentioned this tendency. A lot of what we know about spider behavior is incomplete. They are complex creatures with complex survival strategies. They can and will go hunting for mammals, given the opportunity/need, even if rarely.
For tarantulas, it depends on if they are old world or new world. Old worlds have medically significant venom, and in the case of the Poecilotheria genus, their venom will send you to the ER. The venom may not be deadly, but it is a strong neurotoxin that causes severe cramping for days or weeks without medical intervention, along with other neurotoxin related symptoms like sweating, fever, chills, vomiting and difficulty breathing. All of the other old worlds are medically significant to a lesser degree, but will still make you seek medical attention upon being bit, and all are more prone to bite due to their defensiveness. New worlds for the most part are less prone to biting because of their urticating hairs used for defense and their venom is not medically significant.
Yes and no. Medically significant, sure, but they aren’t really deadly. Might a pokie kill a newborn who was bitten while on a neonative intensive care unit? Maybe. But they haven’t.
You could also make an argument that tarantula bites in general should be given medical attention due to the risk of bacterial infection from the bite itself, similar to a cat bite. Those big fangs can transport bacteria deep into the wound. You don’t want to end up in the ICU with septicemia because you shrugged it off with “whatever, it’s only a tarantula”.
@@fetzie23 True, many suspected Brown Recluse bites are really bacterial infections and not caused by cytotoxin. It is a good idea to go to at least an urgent care to get some antibiotic as a precaution and a good topical like Bacitracin for the wound regardless of the tarantula.
Fascinating and very educational. I’m a keeper of both old world and new world tarantulas but don’t keep any true spiders but the information in this video is priceless. Thankyou
@@georgethompson913The true spider term is a bit of a misnomer, since it refers only to Araneomorpha, but anything within the order Aranae is a spider. Tarantulas are mygalomorphs as are many funnel web and trapdoor spiders.
@@drdoolittlefishhobbyist6055If, by “true spider” you mean Araneomorphae, then trapdoors and funnel-webs aren’t - both are more closely related to tarantulas, with all three groups belonging to the spider infraorder Mygalomorphae. “True spider” is a misleading name anyway; the other two spider groups are still spiders.
I’m terrified of spiders but love to learn about them I’m not sure why lol. When I was about 10 I had a fiddleback on my face and didn’t know until it fell off. Took it to the hospital and fortunately it didn’t bite (even though I had a make) but ever since then. The fear got worse lol. Very interesting. But still scares me haha. Awesome video!
Yeah, sometimes. Spiders do what is called a ‘Dry bite’ - A bite with no venom. Often, Dry bites occur when a spider is startled, but not threatened. In these situations, it is indeed not a medical emergency.
@@derpydactyl8098 That may be true for some spiders, even the wandering spiders, but not funnel webs. They will never deliver a dry bite. Heck, you can often see drops of venom already on the tips of their fangs when they rear up in their strike pose.
I'm from Australia and can absolutely assure you that huntsman spiders are potentially deadly. If you're driving your car and you put down the sun shade and a 6-inch fat bastard falls in your lap, that's a potentially deadly situations. The mofos are fast too.

I didn't even feel it when I was bitten by a recluse spider when I was camping in Greece. When I changed my clothes I suddenly noticed that a spot on top of my right hip was swollen and hot to the touch. I looked into the mirror and found the area to be deep purple, almost black. And two little bite marks in the middle. I had no idea what it was, the doctor said it was an infected mosquito bite and gave me antibiotics. Luckily, no necrosis occured. Then the spot faded from the middle to the edge. This typical healing pattern made me realize after some research, that it was a reclusive spider bite.
But this is when the aftermath started. Apparently, I had some kind of nerve damage. Sometimes a sharp pain would shoot into my right leg, and two times it was so bad that I lost control over my leg and fell to the floor. The doctors had no idea how to help me. I could walk slowly, and work at my job. But running or working out caused my leg pain to fire up. I couldn't work out like I was used to, and gained weight. It took literally three years for the leg pain to fade away. Now I'm slowly losing the weight again.
Damn, that was scary. I still wonder how I was bitten.
My guess is that your clothes probably *are* how you got bitten. While you were out camping, a recluse probably took your clothes for a nice place to hide and when you put them back on, it felt threatened and bit you. Checks with the idea that they like dark places to hide in/under
Brown recluse have a numbing agent
Not saying this is the right thing to do, but I’m feeling heated at that doctor for not ruling out the worse possibility, or just plain dismissing the more-likely signs. I want to go back and “thank” that doctor with a good kick from my bad leg, and tell them the kick would’ve been much worse since those bullshit mosquito bites were in fact, and obviously, a spider bite!

I can verify this spider being a cause of car crashes. This indeed happened to my cousin’s wife. Driving, turned a corner, sun in eyes, pulled the sun visor down. Huntsman dropped on her lap. She panicked and hit the rear of a parked bus. As an insect fan, I love big huntsman spiders. Funny enough, despite their size and speed, they are often caught by wasps and hornets. Seen many a wasp dragging a paralysed huntsman to its nest to lay her eggs on it.
But spiders aren't insects.
But they are insect food. I'm sure wasp fans appreciate their role in the reproductive cycle. :)@@ArchangelExile

A huntsman cralled out of the air vents and i almost crashed my ute. Scared the shit out of me.
Bit by a violin spider when I was a kid in Naples, FL. I have a scar on my right calf and it was a brutal ER episode.
I wonder about that. Are you sure recluse live in Florida? Did you know, over 90% of doctor diagnosed brown recluse bites are actually skin infections? True story. There was a book written in last decade by guy involved in the study. Good easy read. Most everything we "know" about recluse is wrong.
I had to google it. Is that a brown recluse?
@@petergalione1414 very likely yes due to the brown recluses "violin" shaped pattern on its head
@@petergalione1414 yes

As an Australian I would also like to say that though huntsman spiders are not medically significant, they are still dangerous. One, they smell fear, and I will die on that hill. Two, when you’re driving into the sun and you pull down your sun visor and a hairy, leggy, incredibly fast, dinner plate sized bit of nightmare fuel falls onto your face, lap or steering wheel… you are going to crash. Spiders do not have to be venomous to be dangerous. This should be considered for future videos, because I know huntsman’s have killed.
EDIT: I AM AN ARACNOPHOBE AND HAVE SEVERE GENERAL ANXIETY. I know spiders cannot smell fear - that was a joke. And I know they are a reason crashes have happened. Yes, ultimately it was driver error due to an extreme fear response, but in Australia, travelling at speed, blinded by the sun, you aren't going to check if it's a huntsman, wolf spider or funnel Web. You're going to react. Also, more crashes are caused by Kangaroos, cows and wombats than will ever be caused by spiders. I have seen people go off the road and get out their car flailing because of spiders. It does happen. So while the notion might seem bizarre or unfeasable, FEAR, EVEN IF UNDESERVED OR IRRATIONAL, SHOULD NOT BE UNDERESTIMATED.
They are cool spiders, but I thank the heavens everyday I don't live in Australia, because if I ever saw one of those in my house I would probably just kill myself.
@@madjack1748That's actually some pretty funny imagery.

@@sarahrupert5320 If it helps, exposure and education can help with arachnophobia. I am afraid of spiders but decided to get a tarantula as a pet.

It's definitely not for everyone but I imagine living in a place with a lot of spiders will reduce someone's fear conciderably
Managing spiders are no joke, I can't believe you didn't talk about them. My cousin Eric was bitten by one and two weeks later he succumbed to management training.

Got bit by a Brown Recluse when I was living in Salt Lake City, Utah. The necrosis is no joke. Called the University to see what the Arachnid professor had to say, he was in South America for another week. Knowing that venoms are either acidic or alkaline, I decided to pack the wound with baking soda. A week later the professor answered my email and told me to put baking soda on it! Lucky guess by me.
Nice!
I live near SLC and everything I’ve read online says that we don’t have brown recluses here. Was it 100% a brown recluse? Did you travel anywhere out of state before the bite? Maybe you could’ve brought it back with you in a suitcase.
I’m not attacking your story or anything, I’m just genuinely curious. Black widows should be the only medically significant spider that we have here and I don’t think their bites can cause necrosis or even allow necrosis to develop from bacteria.
I wonder if we have any spiders here that have venom with the potential to cause necrosis but only if it’s one of those “worst-case” scenario bites like the video was describing.
Very interesting either way! Im going to look into it a bit and see what I can find
No, I'm not 100% on that, could have been the Desert Recluse or a Hobo I suppose. Let me tell you when you see your flesh dissolving the size of a dime, you just want it to STOP! Interesting thing is it didn't hurt. It was in our bed, first night the wife got bit on her index finger, second night I got bit on my nipple AND my junk. Needless to say I was a bit freaked out. Baking soda did the trick!
Brown recluse aren’t in Utah.
You were bit by a hobo spider.
I'm in septic maintenance in Texas, and EVERY SINGLE DAY I see at least one Black Widow, because they LOVE to nest underneath the concrete block the aerator rests under, and I regularly see Brown Recluses in the same areas, though obviously not nesting and not nearly as often.
Nothing has made me more careful around these arenas than going to clean an aerator filter, undoing the screw and lifting the plastic cover off the filter to reveal a brown recluse chilling there inches from my fingers, lmfao.
Love that they both made the list of the only 4 spiders you ever really need to worry about. ;_;
If it makes you feel any better, there are really two tiers within the four horsemen, with recluses and widows tending to be less dangerous, their venom more likely to make you somewhat sick and in pain than threaten your life, than wanderers and funnel-webs which can be aggressive and often send you racing to the ER if they bite.
There hasn't been a verified death from a black widow in the US since 1983. Turns out they are way less deadly when doctors don't load everyone up with opium and whiskey lol.
@@Huuuuuuue Yes, you die from wanderer and funnel-webs mostly because you are far enough in the woods or because it works its way up your body and shuts down all your nervous system and all your muscles, You basically end up dying from the venom getting close to the heart and your body not knowing what to do about that. Once you introduce steroids (ER steroids that is) and lorazepam (Ativan) or diazepam (Valium) to help the cramping stop. I don't know what they give for Wanderers and Funnel webs. Those two in particular are aggressive and I mean their venom is also aggressive. You could find yourself dead in under 10 hours.
@@Huuuuuuuedid a study on funnel webs a while back that venom is no joke hyper aggressive almost all female so even more dangerous and are really smart leaving carcasses of smaller prey at the top of their funnel and chilling outside of it when something goes for it it dives into it sealing the funnel with webs and quickly taking down birds and rats that go for the carcasses
I turn up a lot of spiders during remodels. I don't want to step on them so I usually guide them gently onto a hand and take them somewhere safe. I realized after years of doing this that I had been misidentifying the brown recluses. I had thought they were a small spider, but then I discovered they were as big as the common house spiders, and I had probably handled a dozen of them with my bare hands, unknowingly. The trick is to not grab at them; you put down a hand and let it become terrain while you guide the spider onto it.
The six eyed sand spider, a very mysterious arachnid for sure. We desperately need more information pertaining to that species. 👀
They actually bealive it's related to the recluse and the venom is somewhat the same yet more potent however more studies need to be done
Put it this way you don’t want to be bitten with one.
@@trapdoorspider9211 Not least because if you do then it’ll happen in the middle of nowhere, hours away from a hospital.
I think it is 72x more potent than the American brown recluse. I came up with that number but can't explain exactly how.
@@sndspderbytes mentioning no names
But with the Other genus of funnel web starting with H don’t know the proper spelling but I heard from a funnel web collector and dwa licence holder he said there was a certain sp of said genus to have venom 2 to 3 times stronger than the Sydney funnel web. But with the six eyed sand spider I hear it is likely to be seeing said spider on a dwa list some time in the future. If it isn’t already. Bearing in mind I heard this 3 or 4 year ago.
When I was younger I had a spider I'd never seen before come near me, the part that stayed with me was the fact it has such a similar pattern to a "redback" spider or a widow but was pure white. I've never seen a spider like it since, it was both beautiful and terrifying.
black widows can have white or yellow hourglass. the one in my house was whitish yellow
@user-wi9hv2pb2q I live in the UK tho is the thing
I hope this channel blows up, it's so clear, thorough, and informative. Seriously underrated videos you got here, more educational content should be like this. Really looking forward to the next one!!
New Zealander here, while we technically have spiders of the widow family (namely the katipo), the widow spiders we have here are harmless to humans, to the degree that we don't even issue anti venom unless you have an allergic reaction. No deadly spiders in Nz and I love that fact aha
The bites from black widows and recluses usually tend to be uncomfortable and cause sickness, but are not usually deadly, really the only 2 that are a genuine threat to your life are the funnel webs and wandering spiders. Definitely though black widows and brown recluses can be considered dangerous, but not quite on the same level as the other two.
Great video, I assumed it'd be clickbait at the start like the vast majority of 'dangerous spiders' lists as you showed, but this was very informative :)
I mean, very few spiders benefit from killing vertebrates and evolution does it's thing, so it shouldn't be surprising.
Recluses may not be likely to kill anyone themselves, but without medical attention, the infections you will almost certainly get in areas affected by necrosis very well could. Before the discovery of Penicillin in 1928 they were much MUCH more of a threat.
Thank you, was looking to see if someone said it.
This is true, except the Australian Redback seems to be more dangerous than other Widows.
“Uncomfortable” is putting it lightly. The pain is off the scale. Incomparable to almost any other insect bite on the planet. No, they won’t kill most adults, but their bite is incredibly painful.
I love getting recommended small channels and just finding genuine quality content. I don't even like spiders but damn this was interesting and you narrated the video really well. Have my subscription :)
I moved to Australia 15 years ago and was terrified with all the spiders i was suddenly surrounded by and i believed all the random "facts" about how venomous some of them were. Like daddy-long legs being the most venomous, but its fangs being too small to bite humans and white-tail spiders having necrotic venom. I understand them so much more now and am very familiar and fascinated by them and now im the guy people call if there is a big spider that needs to be taken outside safely. Most of the truly dangerous spiders here can be fairly easily identified and avoided. Funnel webs are pretty easy to ignore as long as you dont get too many of them in one spot and around children. Red-backs are always found in garages or sheds so its always smart to wear gloves when moving furniture or stuff that hasnt been moved for a while. Brown recluse/violin spiders are more common in Queensland but seeing them is fairly rare but i met someone who insisted that their spider bite that necrotised a part of their legs was a white-tail and i couldnt convince them that it was probably a recluse. Basically, if you get bit by a spider here, its a very, very good idea to catch the spider that bit you and bring it with you to the hospital if you have any severe symptoms so a professional can identify them
What's funny is people still believe that granddaddy long legs are the most venomous but what's funny is they've extract the venom from them and the venom is not even potent enough to kill small insects😂
As much as I love snakes, I'd be much more worried about accidently stepping on/near a brown snake than any of the spiders lol. But even that is pretty easily avoided.
I agree to an extent. Just don't get bit again trying to catch it. The first bite may have been a dry bite, the second could be a full envenomation and put you in real danger that you weren't in yet. Even deadly bites are rarely deadly in western world with access to hospitals. Most deadly envenomations are not deadly in a modern hospital. Your life does not depend on catching the offender. It can help, but isn't likely to change your outcome. So don't go overboard trying to catch it. More important is getting proper medical treatment before major symptoms appear. If you have systemic effects a hospital will save you whether you have spider or not. Now if you are in the desert 190 miles from the closest doctor, that brown recluse bite just got a little more serious.
@@hi_tech_reptiles To be fair a snake typically doesn't die when you accidentally step on it, just gets agitated.
Its not the spiders you need to watch out for. Its the drop bears.

Arachnophobia- irrational fear of spiders.
I have it, but by learning about spiders, enjoying your video, understanding their purpose and behaviour i have learned to appreciate spiders.
Your presentation is one of the best videos I've seen on youtube - great work, nicely done and well worth watching.
Good for you!
Keep going, and you can absolutely beat your fear through curiosity and exposure therapy. I did it and it was one of the best things I’ve ever done for myself, not only for the thing itself but because it taught me that I can overcome any fear I have, and my thoughts are not reality. Keep up the amazing work! 😊
Fear of deadly or dangerous spiders is entirely rational haha😂
In Australia, arachnophobia is nowhere near irrational
Great video, man! I think you did a really good job. A couple of points:
- Another reason the Atracidae males are so defensive is because they are very clumsy outside their burrows, they’re completely outside their element
- It’s a very small point, and it is accurate to refer to the tagmata of spiders as the cephalothorax and abdomen, but I think there’s a strong case for using the term “prosoma” over “cephalothorax.” “Cephalothorax” means “fused head and thorax,” but there is neither fossil nor embryonic evidence that spiders have ever had separate heads and thoraxes. “Prosoma” is also easier to say, as a plus
- I understand that you plan to release a follow-up video covering the actual danger posed to humans by these spiders and don’t want to steal that video’s thunder, but I would have liked it if you would have mentioned that the majority of Loxosceles bites do not produce necrosis at all, let alone more significant effects, and that deaths by Latrodectus are exceedingly rare. People are exceedingly impressionable, and when you have an audience like this I think a certain responsibility exists to do what you can to mitigate the damage that has been done by fake news. Granted, I do think this video overall does a good job of living up to that responsibility by showing how very few spiders are potentially dangerous, and I have to thank you for that!
Thank you, I do prefer the use of prosoma and opisthosoma, as there is legitimate reason to not use the term cephalothorax or abdomen. I just don't want to cause extra confusion for any newer spider enthusiasts who may already be familiar with the latter two and don't want to be swamped with terminology.
I made a sacrifice splitting this video in two, for sure. Part of me still wonders if it would have been better to release a 45-minute video and just have all the information in one place.
That moment when you correctly guess all the deadly four even before starting to watch the video
I can only think of two, the Sydney funnel web and the black widow. The six eyed sand spider is debatable if that's on the list and I just can't think of a 4th other than something like a brown recluse that can cause allergic reactions or other issues caused by swelling.
U have a lot of respect from me🤝💯🧐
@@Nefvillerecluse bites don’t have to cause allergic reactions to be dangerous.
@@georgehenan853 I've been bitten twice by brown recluses when I was a kid, both times on the foot when I went to go to the bathroom late at night. Where I live in Kentucky they are everywhere. I see them almost every day. But thankfully I just had some swelling the first time and nothing the second, maybe a dry bite so that's why I was thinking maybe it was more allergen related.
No one has ever died from a Violin spider bite, & there are only 3 recorded deaths, worldwide attributed to Widow bites.
So 2 of the spiders on his list are NOT deadly.
Legit one of the best educational videos on spiders I've ever seen, ppl always mystify this stuff so much but you turned it into a simple step by step process.
I'd usually go by habitat but apparently I already had most of those types in my head as dangerous. Widows, recluses, tunnel webs, but I always forget the wandering spiders.
Also pfffft, "wolf spider bites" those things' venom feels like a bruise at absolute worst.
This is great, keep it up, I'm so tired of TH-cam drama and this is the best content right now while I sit drunk in my bath tub.
I love wolf spiders and let them live in my house unharmed. They take care of the bugs that “bug” me. Fiddlebacks on the other hand are kill on sight. Black Widows are usually always outside, so I leave them be.
Thanks, great informational video.
The image of the spider at the beginning of the video has 10 legs, like how does whoever made that mess it up 😭
Lol, I didn't even catch that. I guess we're talking about misinformation, so it sort of fits...
I was going to say "maybe they just made one with really long pedipalps like some tarantulas" but it has those too, so idk what the artist was doing
Same for the Australian Mouse Spider lol
Those aren't legs but pedipalps. Males have very long ones which makes them look like legs.
@@wildlifeisthewealthofnatur5457no it actually has 10 legs aside from the pedipalps and fangs

@@mattihaapoja8203 No you don’t see them often, they’re to shy and don’t walk around like other spiders.

@@mattihaapoja8203 it depends on where you live. I will see anywhere from 10 to maybe twenty a year. We have to check our shoes constantly. The funnel are no joke and you definitely wouldn’t want to get complacent
A couple of tarantulas have medically significant venom...Poecilotheria regalis and Poecilotheria metallica. While not capable of causing death, unless the victim has an allergy or underlying health issues, both can cause systemic effects in humans. I had a P. regalis about 30 yrs ago. Wicked fast and moody. I also have a Brazilian Wandering Spider preserved in formalin. It was super aggressive. It came in with a banana shipment to a local Phx grocery store. I always tell people in stores to watch where they grab when getting bananas. They look at me like I'm stupid. Nice video.
Thank you, yes. I thought about including Poecilotheria in here. A few experts do regard them as medically significant, and they're certainly more dangerous than the new world tarantulas, but I chose to focus on just the spiders have threatened and taken human lives before. It keeps things a lot simpler. Those tarantulas are beautiful, by the way.
There are actually a few more than just those two for example Togo starburst baboon and many more the Togo I can vouch for not fun
No arachnid is aggressive towards humans. They can be defensive. They can be aggressively defensive. Just ask anyone with an Obt or Orange bitey thing. But none of them are aggressive to non prey animals. If they waste their venom on us, they may not have it when they get attacked by predator or find a tasty meal. It takes a long time and a lot of energy to make, so they really only use it defensively. If they are being "agressive," they are scared and hoping their erratic behavior will make you leave them alone. That is the goal of aggressive arachnid behavior. Sometimes they are just trying to find a hole to hide in too. That's why Solfugids or Camel Spiders (not spiders, or camels) run "at you." They are running at your shade hoping to find a place to hide. But people anthromorphizing them see it as aggression.
My dad worked in groceries in 70's and still talks about the spiders in the bananas. Now I'm wondering which ones he was finding and wish he would have started breeding colonies. When I tell him that he looks at me like I'm an alien. I don't understand how arachnids don't bring joy to everyone. They are so fascinating.
That will be your little secret. After more than 50 years of being a spider fanatic, I can say with confidence that OBT's, which I have owned, along with about 3 dozen other tarantula species, is indeed aggressive towards humans, as are brazilian wandering spiders. Solifugids, not so much. They're just looking for shade. True, most are simply being defensive and showing a threat display. Yes, I know about wasting venom. You're not the only one here that knows arachnids.
Absolutely amazing video! I’m a huge spider nerd and have kept many species. This video is so concise and informative. Also, it’s very detailed! Seriously amazing!!
Hey brother. Really wanted to say this was a great video. Hope you make more. Love how informative and how much effort you put into this.

Actually same, I’m stupid
Very cool presentation style. You’ve got a great voice and exciting intonation. Following!
I always found it so fascinating how such tiny miniscule animals like spiders and scorpions evolved Venom so potent that it can kill a horse/human. It's understandable with snakes, given they're dead in the center of the food chain and deal with everything from cats and hawks to wolves and mountain lions, but spiders really only have birds and small mammals at the absolute worst.
Ain't no kill like overkill, eh? You see similar in some plants, too. They generally only have to worry about bugs, but some of them go crazy in their defenses.
A big part of it is that the spider bite itself doesn't do much physical damage, whereas on snakes they have big fangs to transfer the venom which will go deep into the small-medium mammal's body and could be directly injected into the area their venom will do the most damage. (muscle toxin, tissue toxin, targets organ function etc.)
Spider venom almost always enters through the surface-level bloodstream not directly into muscles or tissue or organs. Evolutionarily this means that spiders have had more time to perfect venoms because the way in which the venom is applied remains constant. In snakes, since the venom is applied directly in the zone where it works (on prey not on human bites) and since the bite itself is like being stabbed as well as being poisoned, their venom doesn't need to be quite as potent to be just as effective.
@zehkiel8018 Some plants! Parsley has about seven deadly lookalikes on its own, even wild carrots are poisonous in many cases. its ironic because mushroom hunting is so demonised, but plant foragers are actually far more at risk
@jansonshrock2859 That comment was bangin by the way. Where did you come across this?
@@DG-iw3yw I suppose they'd both honestly be pretty risky ventures. One is just viewed as wholesome and normal and the other as strange.
This is a really high quality, informative and well constructed video! Really looking forward to seeing more! Keep it up mate!
It's always great to see another creator in the space give their takes on arachnology but the Widow and Recluse really aren't that lethal at all, except in small children and the elderly, and are mostly just painful. They also have a tendency to dry bite as well, so your chances of being envenomated are also very low. Sydney Funnel Weavers and Brazilian Wandering Spiders are definitely no joke though. Overall doin great, just wanna help keep your information accurate to better serve the audience :)
Yup! That tends to be true of most spiders, regarding the age range. The most serious case of a mouse spider envenomation was on a small child, the "record breaking" 15-minute kill from a funnel-web bite also involved a young child, and Phoneutria Wandering spiders seem to be incapable of killing anyone over 7 and below 70 years of age according to the medical stats.
the biggest issue ive ran into with recluses and widows is that they are pretty easy to accidentally disturb. speaking from experience in texas, the recluses LOVE hiding in drawers or cupboards. this combined with the necrosis risk provides a big threat to many underdeveloped communities. wood piles or trash heaps have to be flipped a few times before you can even go near them
@@lucasvinson982Yeah we get recluses and widows in my area, and the recluses are everywhere, they come inside too. Luckily I've never been bitten so far! The widows stay away from people, and it's pretty obvious if you touch one of their webs (vs another cobweb spider) since their webs are harder to break.
@@arachnorion my dad and uncle used to catch sydney funnel webs and send them in for milking. One day they were collecting spiders and my uncle was bitten. Grandma was furious but he was saved using the anti venom that he had collected.
I also pulled one out of my dogs mouth... My dog was unfazed and I was disgusted
Recluses may not be likely to kill anyone themselves, but without medical attention, the infections you will almost certainly get in areas affected by necrosis very well could.
I live in the hotbed of brown recluse spiders in the US, they have this horrible rep as super dangerous but at the same time those of us who live around them know they are some of the laziest, non-aggressive spiders that exist, unless one gets into your clothes you pretty much will never get bitten, they're a totally chill to the point of being boring, I literally see them every day and I've been bitten once in my 50 years and that was when I was young and was crawling around in a crawlspace below a house, I crawled through at least 100 of them and one took the time to bother biting me, and if you get bit the odds of it becoming bad is quite low
Amazing and informative video. I love your enthusiasm on these spiders along with your calming voice. Earned a sub
First thought as an Australian was "redbacks and funnel webs", but having a neurological disorder, the way you described the effects of neurons misfiring and causing pain in places it shouldn't was better and more concise than my neurologist.
I really like this style of video, feels like I took a course. The way you presented this was really like I was being taught the information rather than being told it. I love learning about spiders, glad to have discovered your channel man
This was one of the most helpful, informative, and truly scientific videos I’ve found on TH-cam. Absolutely amazing. Going into detail the different venom classifications and how they deteriorate or rearrange cells was an extremely intriguing. I had taken chem 2 in college and remember going over how a scorpion stings venom works on the cells. Truly crazy how it works on a cellular level.
An excellent video with some fine deductions! I am going to say the White-tail more properly belongs in group 3. Science and the medical profession tends to dismiss the harmfulness of these for good reasons. This may be disputed by those that have suffered negative effects and the usual response Is misidentification. However, I used to live in New Zealand where these are now far more prolific than in their native Australia, where I now live. Probably due to lack of predation. I have seen about 10 in the 13 years I’ve lived in Western Australia, whereas it was not unusual to see that many in a day in Northland, NZ. It’s hard to imagine anything else being misidentified as a White-tail in NZ.
These would quickly establish themselves in the new houses we were building at the early framing stage in significant numbers.
I witnessed a colleague sustain creeping ulcers from a verified bite on the outer thumb that gradually moved up his arm in several places below the elbow. There are also plenty of anecdotal cases of this happening.
A physician in the South Island took this seriously enough to be concerned for his elderly patients. Although some of this ulceration may be attributed to the effects of diabetes in the elderly, there are enough instances of healthy people being affected to indicate something else may be going on. There may be other mechanisms at work as the venom toxicity has been shown to be mild. But I know what I saw.
I am also finally healing from an ulcerated bite on my lower leg that appeared after gardening about 3 months ago. This resisted topical and oral antibiotics for weeks, but was almost immediately on the mend after applying active Manuka honey MGO400+. I didn’t feel the bite and remain reluctant to blame anything in particular.
As for the Sicariidae, I worked in Namibia for a few years. These spiders lived in places where interactions with humans were practically non-existent. But I believe there was one recorded case of a bite which led to fatal medical consequences for the affected person. The report listed necrosis leading to amputation of an arm and subsequent systemic organ failures. This report seems to have disappeared in the 15 or so years since I encountered reference to it.
My interest then was driven by a very real desire to acquaint myself with hazardous wildlife in a region I was going to be spending much time in. In reality, the real threats were the very large and venomous Parabuthus scorpions and other flavours that were everywhere, snakes such as the Rinkhals, and the Baboons. Not to mention some of the more criminally inclined and well armed locals.
Wow! Thanks for sharing.
I've handled black widows, brown recluse, and Androctonus australis. I've also cuddled tigers. People scare me more than any of them.
I love this video. The fact that it talks about the actual component of the venom indicates how trustworthy this channel is. And the use of scientific research makes it even better. Its not just someone bored oppening Wikipedia (nothing personal Wikipedia is great but using just Wikipedia is very bad for researching). Keep it up
The fact that funnelweb venom seems to specifically target primates is particularly bizarre because Australia had no native primates before humans arrived.
what if the funnel spider killed them all lol what if it used to be like 50x the size and was hunting down and killing monkeys
Great video, and really great speaking and annunciation of your words. Just thought it was worth complimenting on.
Good stuff!! To my view, dangerous spiders arent just the ones that could hurt me, but that, for example, could hurt my dog. Perhaps some venoms arent a thread towards adult humans, but are for kids. It would be great to know more on that if sometime you need an idea for a video! I liked this one a lot
I doubt he would make such video. It is weird but fans would protect their subject from any negativity creating echo chamber.
Ethics will prevent such information from being found out.
If a child dies to a spider bite that wouldnt kill a adult it will be attributed to something else unless through some miracle the kid gets bit, captures(not smushes) the spider and the parents dont throw it out before the child dies (because if the child survives it will be considered a sudden flu or food poisoning from eating too much dirt or the like) and on top of all that the parents bring the spider to a spider expert and on top of that the spider expert would need to believe the word of a (deceased) child over his own ;about spiders of all things; to even consider it as a possibility and maybe start testing the hypothesis.
TLDR: the info doesnt and probably will never exist about such a specific thing.
The analogy of four horseman spiders with the topic of the video and the thumbnail that was used is quite funny to me.
TH-cam algorithm actually being decent for once. Love the content my guy.
My arachniphobia is so severe i was having awful anxiety even just looking at the photos of spiders you put up.. but i stuck through with it because this was an interesting video and i very greatly enjoy the college style presentation youve done!
Also, I live in Oklahoma now and lets just say i didnt have to deal with nearly as many spiders when I lived in Alaska 😅
Ive actually seen a banana spider at the shops. Bro was flabbergasted at being in a grocery store
I have heard “banana spider” refer to 3 kinds of spider: the wandering spider (deadly), the yellow sac spider (annoying but ultimately harmless bites), and the golden orb weaver (probably the biggest non-tarantula in the USA, beautiful, enormous, idk anything about the bit but they were not mentioned in the video). Most of this is local dialect and varies by the region, so if I’m in Texas, it’s probably the Golden orb weaver; if I’m in the Midwest, it’s probably a yellow sac spider; otherwise it’s a toss-up because most people I meet don’t know one spider from the next and I can’t pin down a certain region that calls the wandering spiders banana spiders.
Also glad to see that jumping spiders are not mentioned here because they are cute, friendly, and harmless.
This was a great and informative video! It’s always great to see someone present honest information about these animals, they have been subject to misinformation and sensationalism far too long. I would also like to add that fatalities from Loxosceles reclusa (the brown recluse) specifically, as well as Latrodectus as a whole, are vanishingly rare, and only prove deadly in a tiny minority of bites. Additionally, funnel webs have not caused any fatalities in over forty years, and with treatment, the survival rate is 100%. Even before such treatment was invented it was more likely than not to survive a bite from an Atracid. In the case of Phoneutria, they rarely even cause severe symptoms to begin with, with the vast majority of bites not causing the crazy symptoms associated with this spider. Also, the first image you used for Phoneutria is actually not a Phoneutria at all, instead being a spider in the genus Cupiennius, which are harmless and more closely related to fishing spiders than wandering spiders in the family Ctenidae. Finally, it is incredibly easy to not be bitten by any of these spiders. There are simple precautions that can be taken to avoid negative interactions with these animals, and for the most part, they do not pose a significant threat to human beings. Overall, this was a great video! I just wanted to say a few things :)
Hey, thanks so, much. I will absolutely add that correction somewhere regarding the Ctenidae spider that wasn't Phoneutria. Thanks for catching that. All of those points you made regarding venom were originally in this video but got cut because I couldn't get the run time low enough. That's why there's a part 2 coming really soon.
Edit: Cupiennius isn't Ctenidae. I stand corrected. The eye pattern threw me off here. Can I ask how you identified that specimen, so I can use similar techniques in the future?
@@arachnorion Alright sweet! Although the Cupiennius are in the family Trechaleidae, though I’m pretty sure they were originally thought to be in Ctenidae, they do look rather similar! Anyways, I loved this video thoroughly, I have subscribed and will patiently await the second part :)
@@arachnorionAlso I just noticed your edit! Well I mainly identified this specimen simply from the coloration, as I recognize Cupiennius coccineus, but generally the best way to tell them apart from Phoneutria is to take a look at their chelicerae, which have vertical stripes going down them. Phoneutria usually don’t have these! I’m not entirely confident it works with every species of both genus as I don’t know every single species in both genera, but at the very least the most recognizable ones can be identified easily going off of this rule of thumb! Hope this helps, and I apologize for not seeing the edit before :)
I really like the way this video is set up like a lecture w slides. It was a lot more digestible to me bc of the format helping remind my brain this is for learning not entertainment w my ADD and excessive background content watching. Just helped me focus a lot fr
While I'm not afraid of spiders, it better not come crawling around me.
I got bit by a fiddle back and the necrosis from it was exactly like you described and it’s been hard to find proper information on what happened or why it happened. I appreciated this video greatly!
For those who don't already know, the brown widow is harmless and helpful. I used to work in an overgrown greenhouse that was swarming with them. I must have been bitten by them many times but it's not like I could tell those bites from the mosquitos and ant stings.
Age also has alot to do with how you react to the venom.
Science wasn't really interested in the brown widow, so information slowly dripped out over many, many years, hard to keep up with, hard to fully understand, plain, and simple, not enough drama??? It's like the servil in Africa. Why talk about the Serval when you can talk about lions, leopards, and cheetahs. I definitely appreciate your first-hand knowledge!! I didn't realize the Servil existed for many years. The wild dog was much easier because they traveled in large packs. Making them more capable of killing large prey!!
They are venomous too. Though considered to have milder venom, and are unlikely to bite like the others, they still have venom and should be treated as such. Which to me means pick them up and talk to them. But you do you.
^ To be fair though, all spiders are venomous.
To start a compliment: Good presentation. enjoyed this even though I do have a few corrections for you
spider 1: Latrodectus - there have been no confirmed fatalities since the start of accurate recording in the 70's. the closest to come to that is the red widow (Latrodectus bishopi) who's neuro-toxin venom can latch onto nerve clusters and give recuring symptoms for the rest of the victims (otherwise long and healthy) life. This misconception of the lethality of black widows is thought to have come from the treatment that was historically used. the treatment would be to dose the victim with laudanum, in some cases this would be given in such a high dose that the victim died of overdose, not the spider bite.
Spider 4: Loxosceles - Again not a single confirmed death has occurred from these ever, not even from laudanum treatments. they are unpleasant and absolutely medically significant, but not fatal.
As an aditional, I have been bitten by a steatoda nobilis, it was not pleasant. a weekend long migraine combined with severe contractions to my neck and back muscles to the point that the hospital thought I had contracted meningitis. Lumber puncture confirmed it was not and I later found the spider that bit me. She ended up having a very impressive web in my window and I was mindful of her (and even gave her a few pest insects as food. she would give this funny little butt wiggle when lining up to strike the prey) and there were no other bites. I named her Veuda. Though she died of natural causes one of her offspring (also a female I have named Solara) now lives in a different window and continues to keep my home pest free.
Thanks for your comment! I love when people share stories of their symptoms after bites. It makes the event a lot more personal.
As for your corrections, part of what makes gathering bite data difficult is judging what qualifies as confirmed bite cases. I think there are a couple of inconsistencies in what you're presenting. For example, the study I'm linking below reviewed over 20,000 Loxosceles bites in one state of Brazil over a 7-year period and counted 7 deaths. The fact you say there are zero deaths ever makes me think your standards of what you consider a "confirmed bite" are very high. This is fine, but by the same standards, your own S.nobilis bite would be suspect of credibility, and I would argue no one has ever died from a Phoneutria bite either.
You mentioned L.bishopi as the widow that comes the closest to having fatal venom, but this seems inconsistent with your other comments. What are you using to judge the spider's venom? Is it the report on J.Hollenbeck's notes after he reportedly sustained a bite? Because this would not qualify as a confirmed case under the previous standards, and if this is where we're moving the goalpost, I would then argue TONS of people have died from Loxosceles and Latrodectus bites. I'll link a case from a medical journal down below as an example.
Zero people ever having died from Loxosceles bites might be correct is we exclude certain data. Several people having died from Loxosceles bites is also correct if we choose to include certain data. What's important to me is that we stay consistent across all spiders when choose which studies to cite.
I'll probably make another venom video in the near future. I'm loving how many well-read individuals are showing up to comment, and the interesting points being made.

@@arachnorion Agreed citing sources is very important. I'm going on the CDC records for the 'death count' of both widows and recluse.
As for the red widow, there is little official data, granted, however what little there is does corroborate my statement on the effects as well as patient testimony.
Both false and true widow species have been getting a real bad wrap in recent years when the numbers just do not bare out the hype. Nobilis are wonderful houseguests and will largly stick to their webs and will even retreat to their 'burrows' (or in a house it might be better to call it a hidey-hole) when they see a human looking at them. A reaction both documented and personally observed.
I was surprised that you didn't mention the European tube web spider (Segestria florentina) I remember a few years back these were often being mistaken for funnel web spiders. I hear their bite is fairly potant but not considered medically significant. (thinking a 2 on your chart). I personally think they are beautiful with their glossy black head and the brilliant green stripe on their pedipalps. Personally only encountered one in the wild, but was not disappointed.
(personal note: Solara earned her keep last night and got rid of an annoying house fly just before I dealt with it myself. Gotta love those really strong trap lines they make)
Thing is, going off of "confirmed deaths" or "bite to lethality ratio" is misleading to rate their true lethality. Fact is most spider bites are irrelevant because they don't often inject enough venom before escaping due to being such small creatures that would rather get away from the threat. Often they will dry bite and inject no venom at all. We are not their prey. They only bite quickly out of fear and do not stick around to ensure a fatality, as that prolongs the encounter and puts them in danger.
However, if you look at their actual venom potentials rather than bite records, you'll see that they are very lethal. Academia concludes even the widows, among the weakest of the four, as 15 times more potent than a rattlesnake's venom drop for drop. Problem being they are so tiny compared to a rattlesnake that it doesn't really matter. But that is a staggering effectiveness.
So its not like calling them extremely deadly is misleading at all. When a creature can kill up to exaggeration 120 septillion rats to the power of 10 with a single drop in a laboratory setting, its safe to say they are deadly, regardless of how ineffectual their bites often are when applied in real world, because their priority is to escape you, not to waste their precious venom on non prey.
It would take a special set of circumstances for dangerous bites to occur - if spiders are trapped by pressure between a surface and a body part only then does it become dangerous as they have no other choice than to give a sustained bite to the fullest measure. Instances like this are rare and only when someone is leaning on one or they are trapped in a shoe
@@DiamondxStyles By your set of data then apples should be banned as they contain cyanide or onions as they contain produce aspirated sulphuric acid where as if we ask "How many people die per year from the toxins in apples" you find the answer is.... none. this exact type of science led to the tomato being banned in the 1700s as they are in the same family as belladonna.
it is MUCH more factual to look at the very real numbers from the real world asking questions like "how many bites from species x directly lead to death". If the black widow is a lethal species then how are the presenters of 'kings of pain' still alive after forcing a bite? Feel free to find the video and witness it for yourself.
I'm not saying that the venom isn't lethal in sufficient quantity, but that isn't the question we are answering. The question we are answering is "is the spider's bite able to kill a healthy human?". So far I'm only aware of 2 species where the answer to this is yes.
Rather than looking at what if, we need to look at what is.
To put an amusing and extreme example on this from a real world example: Shipping crates of bananas has set of port authority alarms for nuclear weapons as they are radioactive, however, this level of radiation is not harmful in the dose people are exposed to it in. it takes a shipping container amount to even become registered. that is more than a person can eat in their entire lifetime!
Thank you so much for your in-depth knowledge Abt this arachnids. I recently came across a very large black spider and due to fear I had to relocate to another place for the night. I really don't know what type it was but it was just too large. I truly enjoyed your highly educative videos. Thank you.
Killer video... Love the juxtaposition of the four horsemen with the fearsome and funny little arachnoid 'faces.' ✨🕷
If by funny you mean terrifying, I agree.
@@ArchangelExile adorable
Not surprising the Eastern Mouse Spider and Funnel Web have similar venom; their taxonomy is very closely linked to each other.
Good video. I have a couple of comments though:
1) 12:30 is Cupiennius getazi, not Phoneutria sp.
2) 26:49 it is worth noting that this is outdated literature. The abstract refers to both New-World and African Sicarius sp. This genus has now been split into New-world Sicarius and African Hexophthalma. The relative toxicity of the SIcarridae family (Sicarius, Hexophthalma, and Loxosceles) is quite contentious, with some studies (including the one you showed) suggesting that Sicarius venom exhibits lower levels or no SMase D activity compared to Hexophthalma and Loxosceles, but other studies indicating that there is comparable activity but the molecular mechanism of action may be different. Further work is needed, but it seems currently that there is a non-negligible difference in toxicity of the venom within members of this family.
I actually own a couple of Cupiennius sp. and a Sicarius thomisoides. The latter is about 2ft from my face as I type this!
Thanks for the reply! I'm super late when it comes to posting my research sources for this video, but I intend to add a note about that Cupiennius spider. Someone had mentioned it before and I was unable to link it to one of the (is it 9?) Phonuetria species, leaving me to believe it was indeed Cupiennius. Thank you for also mentioning it.
In many of my previous recording attempts, I had mentioned that African Sicarius spiders had been reorganized into Hexopthalma, but in the end I decided against mentioning it, since it had little to do with the point I was making (phospholipase D is found in every genus of Sicariidae), and I didn't want to confuse people by throwing out every fact on these spiders all at once. At least Ornatus is still in Sicarius, so the main point of the paper is consistent with the current nomenclature.
@@arachnorion Hi, no worries! Glad I could help, if only a minuscule amount. Perhaps I am too close to the subject, but I think the genus split is relevant to the point you are trying to make, since you are discussing relative venom toxicity, which seems to be variable between the two genera. The same group which published the 2013 paper you presented also published one in 2021 which argues that there is evidence for a differing mechanism of action between SMase D in the genus, which may explain some interesting observations in their activity. I understand why you didn't do a deep dive here, but I think conflating the two genera when talking about toxicity is missing some key detail.
But either way, a great video and one I think is important. Spiders get a hard time considering their relatively low venom toxicity compared to snakes and some species of scorpion.
I've been bitten by a brown recluse before, it was on my lower abdominal area about 5 inches to the right of my bellybutton. I didn't realize that I had even been bitten (more than likely whilst I was asleep) until a day later because I started feeling a sharp pain and noticed that the bite area had GREATLY swelled up (and I mean BIG TIME SWELLING) then when the necrosis set in after the swelling had greatly gone down it LITERALLY looked like someone had shot me at point blank range with a .45. I LITERALLY had a hole on/in my stomach slightly larger than the size of a quarter and I could fit at most about half of my finger in it (I know this for sure because I treated and cleaned the wound twice a day using peroxide and neosporin, couldn't afford to go to the doctor/hospital, and I'm a 6'4 man with some BIG hands). The pain from the bite itself had faded away but if I bumped into anything or got poked blah-blah-blah HOLY $HIT it was one of THE WORST pains I had ever felt in my entire life!!
It took me about 3ish weeks, if I remember correctly, to make a full recovery as far as the literal hole in/on my gut goes and surprisingly I didn't experience any vomiting but did have the chills with slight fevers here and there.
So glad we don’t have those damn funnel web spiders here in the states.
They have way too many venomous things in the land of Oz.
I think you mean Aahz
Yes, we no longer sell them as children's pets, and blue ringed octopii are falling from favour in kindergarten displays of late.
In South Carolina, we do have lots of funnel spiders, they just aren't these big, onyx-looking ones. Ours are thin, brown and ungodly fast. They get pretty big and some of them literally can move out and in of their funnel so fast that you can't even react. I don't think they're very deadly, but either they kill losts of other large spiders or they'll shed in some way, because you'll see at least 1 old spider husk in each of the larger ones webs. They always make them against something, so it looks like the swirl of a drain sucking water down into a little hole against your house or woodpile, but - there was one noteworthy year -- a long time ago -- where they must've had some freakish population boom and you'd see their webs randomly strewn about all over the woods every morning, when they were all covered in dew --- like a bunch of miniture tornados. We also have these big bodied yellow spiders that live near swamps and marshes that people call bannana spiders, but they definitely aren't the kind in australia, because they make massive webs up very high and aren't that huge, although they can easily get as big as your hand.
This was an awesome find! Thank you for a very entertaining and enlightening presentation.
Subbed! Great content! Cannot wait to see more from you!
This video was great man but if i can give lne small recommendation try adding stock footage of the spiders youre talking about doing various stuff or just different images as youre talking, such as the size difference between male and female latrodectus or paraxial fangs next to diaxial fangs
But again i loved the video and definitely learned a lot
I have a cousin that's a few months younger than me and she was bitten by a violin spider at a very young age. She ended up getting a MRSA from it. Luckily she survived, but it was scary seeing her so sick from a spider bite.

I work at a summer camp in Mississippi called Twin Lakes, and like a lot of places, we have had sightings of fiddlebacks and widows. Since camp is a place with a lot of younger people (i.e children ages 5-15), it can be sometimes kinda dangerous to do activities such as horseback riding and ropes due to the really high population of these spiders. I know that they are not out there to hurt humans and with good supervision can be avoided and left alone, but there’s always the chance that a rather adventurous child goes off and gets bitten by a “pretty black spider” that he/she decided to mess with.
I work the horses activity and I once saw four black widows together on a fence on our riding ring. I had not only never seen them up close before, but also not in that multitude!
Brilliant video! Nice job.
I have been bitten by a Red Back by accidently put my hand in her web. All it did was to make my finger swell and get stiff for about a week. I was bitten by an Australian trapdoor earlier this year. I reacted badly and the bite area went black and it was like a surver burn. I got sick and had a recurring rash on my leg for around 3 months. I was treated with antihistamine steroid course as my doctor thought it was a allergy to the bite.
I have a deep respect for all poisonous spiders, especially after this year.
My husband used to be an installation tech for Dish, so he’d have to go inside of houses to check out connections and stuff. There was one particular house he went to in Detroit; run down, but the owner had a really nice TV. Hubby went into the basement and in one spot, he thank God looked up before it was too late because there was a brown recluse in a web, plus egg sacs that had hatched. He immediately called his boss to explain what was going on, ‘cause hell no, he wasn’t risking anything. He let the home owner know he had a brown recluse infestation, which he needed to take care of, and that he couldn’t do the job. He dipped. That story is embedded in my brain.
I had 3 separate hatches of violin spiders under the front stairs. within a week the front stairs were turned into solid concrete. they are still around here and there but not in the hundreds anymore and the few that DO get inside are eaten by the cellar spiders which works out wonderfully.
nature has so many ways of balancing itself out it is kinda crazy.
Saw "The Four Killer Spiders" and thought this was a band, clicked thinking I'd hear an album I've never heard before. Instead, I found thirty three minutes of phobia reminders. Lol, oh well still watched it.
Any other arachnophobes watching this? 🥲
This video immediately grabbed my intention as a spider enthusiast and compelled me to click on it and not ignore as poorly researched fear mongering clickbait. The thumbnail focus on eye patterns told me before even watching, that you know what you are talking about. Liked for the algorithm to spread this around instead of clickbait top 10 content farms
Nice to see a well researched and factual video for a change. For killer 4 though, rather than using the genus Loxosceles, I'd have used family Sicariidae, which Loxosceles spiders are part of instead as the African six eyed sand spider (Hexopthalma hahni) is said to be the most dangerous spider on earth. In spite of this great video
I strongly considered it! The reason I left it out was for consistency. People tend to overhype the danger of some of these spiders when the data doesn't support it. It felt wrong to point this out, only to then cite a case of a spider with 2 or 3 suspected bites and no confirmed ones. I legitimately believe Hexophthalma and Sicarius might surpass other spiders on this list in terms of venom potency against humans, I just don't have the evidence to swear by that idea just yet.
@@arachnorion I can absolutely see your point here. The fact that there is very little data in regards to the threat Sicarius and Hexopthalma pose, it was probably the right decision to make. Loved how you used Atracidae as a family for the Aussie Funnel Webs as most would've cited Atrax robustus on its own, where there are 6 Atracids which have caused severe life threatening envenomation symptoms in bite cases so I tip my hat to you on that. You've got my sub for sure man as your video was factual and on point compared to the thousands of videos out there that are pure sensationalised misinformation. Keep up the good work dude.
I'm a little skeptical that it's the most dangerous in the world. They are a species of recluse, so I've read, and also that there are no proven cases of humans being bitten and apparently only 2 horror stories about them weren't confirmed bites. This was on research I did from other spider experts. Not saying they aren't dangerous but most dangerous in the world is a stretch, eapecially since it was never recognized by Guiness like the wandering spider and Sydney funnel web were.
Thank you! I got a bunch of yellow sac spiders living in my bathroom, they’re cool little guys as far as I’m concerned, haven’t been an issue so far.
Arachnorion remember me when you're famous
Black widows also love cardboard and barrels that are turned upside down Ive found dozens of them over the years where I work. They are certainly frightening looking spiders! 😬😳😖
Also my sister was bitten by a fiddle back spider years ago and had a lot of trouble with it the doctor couldn't get it to stop breaking down her leg where she got bitten and even now she has a crater where it was at that is pretty deep and really darker than the surrounding skin. 🤢😬🤷🏻♂️
The lesson from this is leave spiders alone, and they will leave you alone
You are right. But it is an over simplification. Most people's last thought is picking up spiders. A majority of bites are from accidental contact. I got a black widow dry bite in Moab one night looking for Scorpions. It had a web across a part of trail narrowed by large boulders. I triggered it and got tagged in shin. After contacting a toxicologist I know in Europe that was awake I waited by trailhead for effects of venom. Was told after 5 hours of no symptoms I could consider it a dry bite. It was thankfully. I hold them fairly regularly and have never been bit. Go on a hike at night, and boom. Sometimes it's hard to keep your distance or even know they are there.
Spiders are amazing creatures.
I'd imagine many Recluse bites are often similar as they may reside in clothing at times
Not always true. Once I opened a closet I rarely used, and there was a huge, brightly colored garden spider, with a web that covered about the whole doorway.
I said, "nope," shut the door, and forgot about it.
About a week later, as I'm dozing off for the night, I get a stabbing pain in my butt. I slap whatever it is, get up, turn on the light.. it was that damn spider. It had left its web and gone hunting for animal blood in the night. Nothing I've seen written/spoken about garden spiders has ever mentioned this tendency.
A lot of what we know about spider behavior is incomplete. They are complex creatures with complex survival strategies. They can and will go hunting for mammals, given the opportunity/need, even if rarely.
Didn't know your game bro, but you killed it, keep going
Takes the phrase “Death by Powerpoint” to a whole new level!
Seriously, great job! Keep it up!👍
This video was the best video I have ever seen on dangerous spiders. You just earned a subscription.
For tarantulas, it depends on if they are old world or new world. Old worlds have medically significant venom, and in the case of the Poecilotheria genus, their venom will send you to the ER. The venom may not be deadly, but it is a strong neurotoxin that causes severe cramping for days or weeks without medical intervention, along with other neurotoxin related symptoms like sweating, fever, chills, vomiting and difficulty breathing. All of the other old worlds are medically significant to a lesser degree, but will still make you seek medical attention upon being bit, and all are more prone to bite due to their defensiveness. New worlds for the most part are less prone to biting because of their urticating hairs used for defense and their venom is not medically significant.
Yes and no. Medically significant, sure, but they aren’t really deadly. Might a pokie kill a newborn who was bitten while on a neonative intensive care unit? Maybe. But they haven’t.
You could also make an argument that tarantula bites in general should be given medical attention due to the risk of bacterial infection from the bite itself, similar to a cat bite. Those big fangs can transport bacteria deep into the wound. You don’t want to end up in the ICU with septicemia because you shrugged it off with “whatever, it’s only a tarantula”.
@@fetzie23 True, many suspected Brown Recluse bites are really bacterial infections and not caused by cytotoxin. It is a good idea to go to at least an urgent care to get some antibiotic as a precaution and a good topical like Bacitracin for the wound regardless of the tarantula.
Fascinating and very educational. I’m a keeper of both old world and new world tarantulas but don’t keep any true spiders but the information in this video is priceless. Thankyou
Tarantulas aren't true spiders?
@@georgethompson913 no, your wolf spiders and funnel webs, trapdoor spiders etc are all known as true spiders.
@@georgethompson913The true spider term is a bit of a misnomer, since it refers only to Araneomorpha, but anything within the order Aranae is a spider.
Tarantulas are mygalomorphs as are many funnel web and trapdoor spiders.
@@drdoolittlefishhobbyist6055If, by “true spider” you mean Araneomorphae, then trapdoors and funnel-webs aren’t - both are more closely related to tarantulas, with all three groups belonging to the spider infraorder Mygalomorphae.
“True spider” is a misleading name anyway; the other two spider groups are still spiders.
i have wolf spiders living in my apartment and I let them hang out, mostly in the hopes that they'll eat the moths.
They are definitely good to have on the house. They hunt insects and spiders you don't want.
I’m terrified of spiders but love to learn about them I’m not sure why lol. When I was about 10 I had a fiddleback on my face and didn’t know until it fell off. Took it to the hospital and fortunately it didn’t bite (even though I had a make) but ever since then. The fear got worse lol. Very interesting. But still scares me haha. Awesome video!
Getting bitten by a funnel web is SOMETIMES a medical emergency? Mate…
🤣Not sure when it wouldn't be. Us Aussies know the only reason people don't die now is our anti venom program.
Yeah, sometimes. Spiders do what is called a ‘Dry bite’ - A bite with no venom. Often, Dry bites occur when a spider is startled, but not threatened. In these situations, it is indeed not a medical emergency.
@@derpydactyl8098 That may be true for some spiders, even the wandering spiders, but not funnel webs. They will never deliver a dry bite. Heck, you can often see drops of venom already on the tips of their fangs when they rear up in their strike pose.
@@matthewcullen1298Nonsense
