I appreciate that scishow can cover stuff like this without being all clickbait fearmonger-y. Know what I mean?
Yeah 90% channels would have a thumbnail covered in red arrows and circles, a close up of the hosts face, and have a title like "Are YOU Infested eith DINOSAUR Parasites!?!!!? 😱🤮🤢🤢"
Yeah, pretty sure you have hank green to thank for that.
THIS PARASITE COULD BE KILLING YOU NOW! WATCH TO LEARN WHAT IT COULD BE!
@@davel4030 YOU WON'T BELIEVE (how little journalistic or personal integrity we have)!!!

"...50% of living species are considered parasitic." Looking at my co-workers...yep.
Biggest same.
Exactly hahaha
absolutely LOL
Have you meant my family. 😣😣😣
Seems an underestimate then.
WHO IS RESPONSIBLE FOR THAT EXTREMELY CORNY HORSE GRAPHIC I DEMAND TO KNOW
It's amazing isn't it?
I get the "WHO MDE THIS BURGER" vibes
Why are you SHOUTING!
It was a powerful move
The majority of solitary wasps are parasitoid. Every agricultural "insect pest" is targeted by one or more parasitoid wasps. They are valuable to food production.
Fraser Henderson cool
Some people are even arguing that maybe Hymenoptera is more diverse than Coleoptera. Some species of parasite wasps are the smallest insects ever found, measuring less than 150 micrometers. So there's a lot of species to be found
So, why do we use pesticides again?
Gabriel Martins because it’s easier and cheaper than constantly growing predators inside to release outside.
True but...Fk Yellow Jackets regardless. They are like that annoying tough guy who tries to get up in your face.
Me: About to take my first bite of lunch

Yeah the fact is that you yes you have eaten one or more of the parasite waspy cuz they be in hela fruit yummy 😜

Parasites terrify me - anything remotely wormy fills me with rage and fear - but they're also one of my favourite creatures, because they're so fascinating.
and here I was expecting a list of the 6 oldest senators in washington
Dianne Feinstein, Chuck Grassley, Richard Shelby, Jim Inhofe, Pat Roberts, Patrick Leahy. All over 80 years old
He pretty much described Kushner at the end.
What about the president, his daughter and in-law, his wife, his sons...
@@smurfyday Half the country thinks the same about Obama, Clinton and so on. Tribalism is stupid and you're not helping.
@@stevevernon1978 I think politicans need a mandatory retirement age. We dont trust military officers to drive a tank, lead men, fire a gun, or even work at a desk past 65 but we trust senile 80+ year olds to run the whole country and handle the ICBM launch codes
I love how when humans encounter a strange problem in nature, we instantly just assume it's probably our fault. To the point we genuinely have to double check when we realize it might not be.
To be fair with our track record it is a pretty good policy to have

SchiShow: ancient poop!
The SciShow music surprised me because the thumbnail had me thinking I was clicking on a Journey to the Microcosmos video.
Could you do a show on why parasite life cycles are so weird? I'd love to learn more about the selective pressures driving that sort of coevolution!
9:57 could this be the beginning of a new account Horseback Stefan?
Watch out Muscle Hank, there's a new superstar riding into town.
With as much poop talk as was in this video, I’m legitimately surprised that Hank wasn’t hosting it.
9:59 that was amazing xD pls more of that :D
Yes!
Love the pic of Stefan riding a horse. Almost doesn't look photoshopped.
"Parasitism is a winning strategy" Aight, time to scroll through the comments looking for people talking about their exes.
This was great to watch while eating, in the bath.

@@Noodlepony it's the only place my cats dont bother me.
Yep nothing like using the hair dryer tub side to dry my hands so I can operate the toaster and electric grill. But that's only after I swan dive off the sink counter into the tub to make sure water gets into the gfci outlet I bypassed.
PARASITES!!! *glomps*
In my final year of university I got to do a presentation on the Neolithic. I spent an hour talking about parasites, explaining in great detail how schistosoma are picked up, and what the symptoms would be. It was riveting, and I thoroughly enjoyed myself... not so sure about the class though 😎
This is by far my favorite post today :)
My parasites aren't that old, 18 and 22 years old respectively.
Parents or children?
@@lyhenglim6969 You didn't math that out, did you? LOL imagine a 2 year old with that sense of humor and a keyboard.
Like Bot Apparently replying to a joke with another joke is dumb
@@lyhenglim6969 TBH I thought it was hilarious. I had a mental image of This Old Tony's kid wearing his welding goggles and sitting at a PC griping about his leeching parents on FB.
Like Bot Sorry about that snark, I misread your comment
"Coprolite", because "Faecaelite" was just too poopy... :P
Copro still refers to poop!
Isn't that the same thing
Parasites and viruses are fascinating. It's scary that they've been at it since the dawn of life.
They're kind of basic, I mean most of virus don't even have mitochondria
Meeta Verma honestly that’s the amazing part to me, like they’re so efficient they’ve just went the complete opposite way from cellular life and they’re still so successful
you have viruses
Not surprising though. Why make for yourself when you can take from others? Thats basically the evolutionary rationale for them.
Freeloading and griefing has long been the meta.
You should do an episode on the parasitic evolution of corporations and their CEOs. wasps and tape worms cant even come close to those parasites
We used to use "You schistosome!" as a way of insulting each other in university!
Humans: "cheaters never prosper!" Nature: "bend over, humans".
Nature: Hey humans, you sure a look like you have a purdy orifice or ten (if no hole, make one).
30-year-old me before watching: "I just love a good Sci Show video to stimulate my brain!"
My inner 12-year-old 5 minutes in: "Hehe pupae...PYOOPY"
Babies are the sneakiest parasites
Most interesting!! Thanks again for your show. Love it!
Awesome episode thank you!
Why is nobody talking about the fact that sharks apparently poop in spirals??? This is the most important thing I've ever learned.
It's a tie with wombat cubes for me
Lol, yes a truly useful piece of information to take with you on your way.
LMAO THAT PIC OF HANK AT THE END
Thank you, Mr. Bill Mead, for your excellent horse and rider graphic! It brought forth an instant chuckle.
I'd love to see a follow-up episode about ancient symbiotic relationships.
I’m hoping you specify that viruses are almost parasites and potentially have been around as long as cellular life has
A virus is not alive.
Azure'Ra Morganna a virus does challenge the idea of what we consider to be life, but it has organic properties.
I love that the channel has over 6 mil subscribers
This video topic gives me chills
Wow great video thanks for new information, this is a time where we need to be educated individually instead of relying on other "experts"
Parasites are the spawn campers of the natural world.
"It's a legitimate strategy!"
Bravo - outstanding
All kidding aside I had no idea that 1st parasite lived in fresh water really spooked me because I like to wade in fresh water in the summer
The only water that don't have living things in it, including parasites, is UV treated water.
Better you dont know about the parasites that can travel up your urethra then when in water.....
@@anarchyantz1564 Oh I know about them.
@@budmeister Hopefully not from "intimate" experience?
@@anarchyantz1564 at least we aren't some fish species that get their tongue cut off from a parasite only for them to become that fish's new tongue stealing its food and starving the fish that would suck
I was so sleepy when I read the title of this video that I thought it said "6 of the oldest pastries ever found" and was confused when the thumbnail didn't look like a pie
Good lord this video makes my skin crawl.
Are you sure it's just your skin that's crawling?
@@magicalmanfromwonder What'd you have to go and say that for! Now I gotta shave my skin off!
It's not the video. It's the parasites.🦀
tapeworms are the worst 😩😩😩😩😩
my cat got them once from fleas he got outside, and he knew something was wrong so he would lay on my bed with his backside facing me so i could see these little segmented pieces crawling out of him and it was horrifying. i immediately bought tapeworm meds from petsmart, bleached all my floors, and washed my bedding at extra hot temperatures like 5 times in a row. luckily i never caught them. but it was horrifying.
Haha, literally on a horse "hitching a ride" at 9:56
sorry. i tried to watch this twice now and just couldn't. parasites freak me out too much. : /
Thanks for trying! We have some non parasite videos coming this week too. :)
This channel is best channel.
I loved the equestrian photo...
My last landlord was in his 90's, does that count?
It should!! 🤣😂🤣😂
The green caterpillar is what we called Tomato Worms. Of course they aren't worms but we didn't know that. They are incredible eaters and just few of them can strip a tomato plant of all its leaves overnight. That meant that when they were in season we had to go out and check all the plants twice a day. They are very sneaky and hide under leaves; you can find a bundle of little ones are wrapped up together after they have just hatched. My father noticed that some of them were covered with little white stalks that looked like eggs. We brought one inside and waited. It was paralyzed but still alive up until the end when voila! a raft of tiny wasps burst out. Yay, we caught some of the wasps and put them back in the garden. Within weeks almost all the caterpillars had been infected and keeping up with the few left was easy. This was in New England. Imagine my amazement when they turned up in my garden in New Orleans! Nobody there had ever seen them before. There weren't any tomato plants around but they seemed to have immediately switched their diet to hibiscus plants. Noticing that my hibiscus plants were being denuded overnight I looked for some bug that could be eating them and found the little monsters. They are actually quite big, as long as 4", but so well concealed that you have to literally turn over every leaf and look underneath it to find them. They grab on tight so you really have to pull hard to get them off. Warning: If you find one do NOT pick it up bare-handed. They have gigantic pincers that will stick a good 1/2" into your finger on either side and they HURT. It is very hard to make them let go too. Best defense is nice tough gardening gloves and a little pail of soapy bleach water, but it takes them a long time to die so you may have to push them back in a few times if they crawl out. I sure wish I could find some wasps down here!!
You on that horse was hilarious
Okay WTF!? I literally found a Tomato Hornworm on my pepper plant today and never seen one only to see it here a hour later.
I hope you didn't pick it up and get bitten; they have amazingly long and strong pincers, I can vouch for this.
Thank you
Parasites are endlessly fascinating. For those who are interested in the subject, a fantastic high-level overview book on them is "Parasite Rex" by Carl Zimmer.
The guy on the couch can confirm this sound strategy
HANS...GET ZE FLAMMENWERFER!!!
I was today years old when i learned that sharks have spiral shaped intestines. Idk why that's so mind blowing to me.
Recent studies have shown in some zombie fungus doesn't penetrate the brain but does the neural network which puppets them. This means the host are conscious and aware but unable to prevent themselves from rotting from the inside out before being allowed to die once the fungus is ready grow and to release spores
Is it just me or did you think that mole was a bit of dirt on your screen haha
2:59 You can say to someone you don't like or in public forums that something is a load of coprolite. That's as polite as you can get since it's not a conventional form of expression, therefore not derogatory.
I’ve never been more disgusted...
Or enthralled! 😯
Watching this while my stomach hurts for no apparent reason
Goodnight
Though you didn't mention this, brachiopods are not mollusks, and are there own phylum.
Symbiotes next please :)
it's winter here with not much insect food around. i found an adult wasp chomping on a cabbage moth larva.
Fun fact, the largest, Jeffrey Star
*30 year old watching TH-cam about oldest parasites.*
Dad, walking by: “That ‘bout you, son?”
5:00 Actually, since parasitoidism is ancestral to all wasps, it’s at least 200 million years old
Oh wow, with my new headphones I'm hearing bass in the intro I've never heard before! 🎧
Is this comment sponsored by Raycon?
@@sarcasticeggs8998 if it were raycon you'd probably only hear bass
@Autumn Anxiety this IS in fact an ad then?
I don't even remember the brand I bought. I'm poor so these are the first pair I've ever owned.
Small Correction: the wasps you talked about are parasitoid, but not because they only feed on their hosts when young. In fact, a parasitoid is marked by the fact that it necessarily kills the host, as opposed to a parasite which would “prefer” for the host to stay alive.

I watch EVERY SciShow video, and love all the info.
Hmmm.. whomever did the makeup for this video blotched (heehe pun) it bad. A bit too much.

Hi, I haven't been able to find an answer to my question on the internet at all, so I want to ask it here.
I love butterflies and I have a huge amount of nettle growing in my area, so once in a while, I love to find tortoiseshells and caring for them till they turn into a butterfly.
Obviously, not all of them survive, but one situation was really unusual. Two of my caterpillars started to turn black and literally wither. They had a lump inside of them near the head but the rest of the body slowly turned flat. Once they were dead there was a white 3mm in diameter "pearl" left near them. When I first saw it, I was scared to leave it like that so I just dumped it in trash.
But the question is, was it a parasite, and if yes then what kind of a parasite?
Maybe a fly, _Sturmia bella_
www.ox.ac.uk/news/science-blog/whats-eating-small-tortoiseshell#
@@massimookissed1023 Thank you for looking into that! But I think it's not sturmia bella.
The closest picture to what I've seen was this

Parasitic wasps be like: they prey on caterpillars and are killed by other wasps who are killed by other wasps...
So... Maybe beedrill doesn't actually evolve from kakuna. Maybe weedles are supposed to evolve into something more mothlike.
Read the title as Ancient Pastries, was excited for a food history vid, not really too disappointed tho.
Nothing about my boy toxoplasma gondii :'(
@@gb7168 By some counts, up to 20% of people on Earth have Toxoplasma Gondii sitting on their brains right now as we speak. Cats are popular pets. As a bonus, they release things like dopamine that can potentially tweak your brain function.
There is no evidence AT ALL that they affect human behavior other than slightly increasing the risk for certain conditions like anxiety or schizophrenia. We are not mice.

You might want to stop with your opinion, and start looking at actual science.
The pyoopee 🤭
Imagine scientists studying one of your random dumps ten thousands of years later
I'm amazed you didn't mention mitochondria.
After watching the video, my whole body is itching and I suddenly feel weird sensations coming from my stomach. No thanks to you guys. At least it was a very informative paranoia inducing video!
oh god Xenomorphia...it begins! next is Weyland Company!
5:08 Fried and crispy!
It’d be nice to see a video on how parasites help their hosts. I have a vague memory that people with tapeworm didn’t get dysentery or something like that.
I have to tell my parents my lifestyle is NOT UNNATURAL.
some of those parasitoid wasps also mind control their hosts ^_^
Just realized you were talking about pupæ in... poopy... Then my brain said, "Hehehe...he said pupæ..." lol!
we need a cowboy stefan to go along with muscle hank
9:57 I see all your patreons have increased the cgi budget substantially
That's some serious schist
Amazing is it not that parasites found a niche so quickly in the history of life.
I thought this was "Journey to the Microcosmos"
No, this is run the hell away from the microcosmos.
So like a long flat spiral shaped thing of poop or spiraled cylindrical deal, like a normal everyday spring as opposed to slinky?
Xenomorphia...perfection.
Lemme get this straightened, xenomorphs were inspired by parasitoid wasps, and now we’ve named an ancestor of parasitoid wasps after xenomorphs? It all comes full circle, huh
What I want to know about these wasp is what came first the bee like bug we know or the parasite like young ? Either is wild to think of
Probably not the best TH-cam video to watch while eating breakfast. XD
Interestingly enough, parasites are also a good bio indicator for ecosystem health due to the nature of their life cycles requiring sometimes several different host species, when there are less parasites that are known to inhabit species of a given ecosystem, this may indicate that one or more of the species are not present in sufficient numbers for the parasite to complete its life cycle, thus indicating that the ecosystem is being impacted by some other factor.
There’s two types of species, parasites and chumps
You have a really great flow brooo....keep it up
