Actually, CGP got a bit lazy reporting this one. It's true that in 1869, Friedrich Goltz performed an experiment demonstrating that lobotomized frogs would not escape slowly-heated water but normal frogs would (and well before it got hot). However, follow-up studies by (Heinzmann 1872) and (Fratscher 1875) on intact frogs found that they would not jump out of water boiled sufficiently slowly, but would escape water heated quickly. No modern study has ever been able to replicate these early results, so it is not really known how they were obtained. However, zoologists are adamant that it is a myth. It's not clear, for instance, how they persuaded frogs to sit in the pot in the first place (cold or warm) without trying to escape them. In fact, modern experiments _have_ been conducted to determine various frog species' critical thermal maxima, the temperatures at which their movements become erratic and ataxic. Some of these experiments do involve slowly heating water and find that as the temperature increases, frogs become increasingly agitated trying to escape the pot until the critical thermal maximum is reached.
if anyone wants to know why, it's cause we feel heat and not temperature. Meaning, we sense changes in temperature, not temperature itself. That's why cold metal feels colder than cold wood.
Chak Lee That's not quite right. Even cold-blooded animals like frogs maintain homeostasis, so they certainly feel the rising temperature. If their core temperature is too high, even if it is constant at that temperature, they will seek colder places. Apart from that, the temperature of the water will consistently be higher than the core temperature of the frog anyway. This is why in all modern experiments, frogs have done everything possible to escape the warming water until they are so disoriented by the heat their movements become ineffective. (And the reason cold metal feels colder than cold wood is due to its much higher thermal diffusivity resulting in a truly colder temperature of the cold nerves in your skin. It is about heat transfer in this case, but only because the wood does not draw heat away from the nerves very quickly relative to the blood supplying heat, meaning the nerves don't get very cold. When you touch metal, the nerves do get cold. It's not just about how quickly the temperature changes. (Though rapid changes in temperature also do produce more obvious sensations than gradual ones, due to a separate mechanism.))
The Goldfish myth was created by pet stores to justify keeping them in a small round bowl, claiming every time they made a lap it was a new experience.
We actually tested a tropical fish in an aquarium where I once worked. It would swim over to see only me, not others even if we exchanged some clothes, glasses, etc.
It's ironic because knowing a little bit about animal care now (Though admittedly my knowledge of fish is lacking) I DO know that goldfish are actually pretty high maintenance, requiring large tanks to grow into that are kept meticulously, needing regular cleaning and careful feeding schedules.

IIRC the myth was already around, which is why they threw those lemmings off a cliff. They wanted footage of it happening, but got fed up with waiting and staged it when wild lemmings stubbornly refused to end themselves like everyone "Knew" they did.

@@Pennywise12528 I was once told (no citation, sorry) that the myth began when members of a colony of lemmings in northern scandinavia was seen to leap off a cliff one after another, much as the Disney film shows. Little was known about these creatures at the time but subsequent study of this strange behaviour indicated that they instinctively followed well worn paths from their nesting to their feeding areas. It seems that there had been an earthslip which dropped a large segment of the cliffside into the sea and that the animals of this colony persisted in following their instinctive behaviour even though the path had disappeared.
Great vids CGP. FYI: the Lemmings myth is from a Disney documentary that was filmed in my home province of Alberta Canada in the 70s I think. Lemmings are not native to our province and the film-maker has been said to have paid Inuit children north of Alberta to capture the Lemmings for use in his film. He then used tight camera angles and other video trickery to make a small amount of lemmings seems like many and then he pushed them off the cliff from behind. This was because he truly believed in the myth of suicidal lemmings but couldn't capture the behaviour on film. His solution was simply to fake his belief. As I understand it, the original belief in lemming suicide was based on some accurate field observations but as more observations of lemming were made it became apparent that they do indeed have population explosions and many of them to venture out into new territory and this has on occasion led to situations where a pack of them are close to a ledge or something equally deadly and the pushing from the back of the crowd pushed the front lines to their deaths. No indication of them just being suicidal. Just a bunch of mammals pushing into one another like when we humans go to sports stadiums. Put the stadium's edge on a cliff with no walls and the guys pushing to the bathroom would cause other humans to fall to their deaths in the same manner. That's what I've heard here in Alberta where it was filmed and Snopes says almost all the same stuff. I'm pretty sure this is where the myth was born. Cheers.
humans can actually develop echolocation as a study was done specifically on that front, people that go blind and focus solely on sound, on occasion the parts of their brains responsible for registering vision is triggered. and humans can get pretty good at it too, such as determining the density of objects based on clings and clangs when they try it out and even their size.
+John Blood humans dont develop echolocation. every stock human comes with a set of two auricles which allow echolocation through their quantity and shape. our visual sense is just that damn good, that larger ears never meant a huge enough advantage to further walk down that evolutionary path
That's technically true (the best kind of true) But I've tried to find my brother in a room with a blindfold on, and it's really hard to find a moving person, because it's delayed due to the fact that you have to guess where the sound is coming from.
You aren't blind, so your brain hasnt adapted the processing power normally used for your sight into further audio processing. Think about it this way, our eyesight is superior to every other sense, so most of our sensory processing is for eyesight, without it, all that processing power goes straight to hearing and smell, making those senses far superior to a normal human
I once saw a documentary that showed a blind man who does this. What's interesting is that they also tested his preteen son, who _isn't_ blind, and he performed better than expected at acoustic wayfinding. Didn't verify any sources, so don't know how significant that is or what could've caused it, but it was interesting. In another documentary, a blind man actually demonstrated how accurate this skill can be, by drawing his surroundings based on what he sensed with his hearing as he traversed an outdoor area. He was able to tell when he was walking under a slatted roof, for instance. The accuracy of the drawing was impressive.
Didn't the Lemmings myth derive from an old Disney documentary where the film maker, controversially threw lemmings off the cliff? Correct me if I'm wrong - too lazy to google.
+Indubitably actually yes. but he didnt throw them of, they were driven off the cliff. its a well known disney secret, it was also the very first nature documentary ever
***** I'm sorry but thats wrong. a daddy long legs scientific name is Opiliones, while the cellar spider is a Pholcidae. One is a spider the other is not. the main differences is that a spider has two body masses the head and the abdomin are seperate, which you can see in Pholcidae but not in the Opiliones. daddy long legs are also called harvestmen......"Harvestmen are an order of arachnids. Although they are often confused with spiders, the two orders are not closely related. Research on harvestman phylogeny is in a state of flux. While some families are clearly monophyletic, that is share a common ancestor, others are not, and the relationships between families are often not well understood."
Turns out that in spite of what we thought for decades: that bats have amazing reflexes and use echolocation and their vision to gracefully avoid hitting other flying animals and generally...stuff, modern night vision cameras have shown... they hit stuff and other bats basically all the time.
the myth about ostriches cracks me up every time, those motherfuckers are violent, they are more likely to attack you than ever run away, even unprovoked they like being aggressive
Maybe the mother bird won't abandon their babies if you touch them, but one time we found a baby bird that had fallen out of it's nest, and for some strange reason, it imprinted (or at least took a very strong liking to us) and followed us around. The mother bird couldn't find the baby after it followed us for a while (despite our efforts to make it stay), and we found the bird dead from cold the next morning. :'(
The main reason for the "Bats are blind" misconception is, while yes, they can see things, they are notably nearsighted, and use echolocation to make up for it.
I re-watch all Grey’s early videos every few years! They are so great, just gotta remember to pace myself and not bin- ...crap did I just watch 12 in a row?!? 🙄
impwarhamer Actually, it is. There was a teen named Ben Underwood. He became blind at a young age after having his eyes surgically removed. He was able to make a repetitive clicking noise with his mouth to use something similar to echolocation to make a map of where he was. People who lose a sense have their other senses enhanced, so it was possible that it was easier for him to hear the clicking than others. But the cancer that took his eyes came back, so he died recently :(
I thought lemmings suiciding was because of that old piece of film where they're jumping off a cliff. What is not shown is just off camera is a guy with a flamethrower. BTW that piece of film was funded by Disney.
Ostriches, emus, and cassowaries… Stay away, they're giants and they'll fuck you up. Once a boy died after harassing a cassowary. It kicked him and slit open his carotid artery.
+Babylauncher3000 However, he was talking about the bite of spiders as seen a couple of seconds later when he debunked the myth that they can't bite because they have short fangs, because they aren't spiders. So when he said the myth that they were the most posionous spiders in the world, he meant the amount of poison they send through they're fangs which because they send it through their fangs they are in fact venomous. After all, all spiders are posionous if eaten and daddy longlegs are not spiders.
I heard the frog thing about lobsters. the idea was they didn't have a central nervous system (or it was too primitive to detect boiling water) so it was totally OK to boil them alive. They couldn't feel the pain! I always thought it was a myth though.
Munch KING the explanation I heard was that since they are cold blooded and can only sense temperature in relation to their internal temperature, if you raise it slowly enough they won't notice because their internal temperature will be the same as the external temperature.
Lobsters are bugs and as bugs don't have an analogous nerve cells to vertebrae pain receptors and therefore don't "suffer" from pain. They just react instinctively to stimuli. However, just bc they don't feel pain doesn't mean we shouldn't strive to keep the organisms making the ultimate sacrifice by feeding us as comfortable as possible. That's a good rule for society in general
Bugs isn't really a technical term but it does refer only to invertebrates so while crustaceans may have been around for longer and it might be more scientifically accurate to say bugs came from a crustacean lineage rather then all crustaceans are bugs, the word does the job of delineating the relationship between both terrestrial and oceanic arthropods. Unfortunately, as is common with colloquialisms, the term "bugs" also refers to creatures like slugs and snails and earthworms which are of a different and much older lineage then arthropods sooooo.......¯\_(ツ)_/¯
the ostrich is the closest thing to raptors? Really? Allow me to introduce you to my good friend the cassowary. Seriously, riots shields are recommended if you make one angry.
Didn't the "Lemmings are suicidal" myth start from some documentary where the makers deliberately drove the poor fellows off a cliff by scaring them until they did that?
It was a Disney documentary.After finding out about this and other things you probably won't see a Disney movie again and not think about these things.
3:12 CGP: [Removing a brain] And also make them more gullible to common misconception Me: Ahh, Nice insult to whoever is watching... wait... IT'S ME!!!
1:43 Mythbusters did a nice video of that. they had 2 groups of goldfish, and one of them were trained to swim trough loops for a reward as food. the ones with were trained swam trough the loops much faster than the other ones (with were control group)
I believe they only did that because the myth was already widespread - the directors couldn't find any lemmings jumping to their deaths in the wild to film, so they knocked them off a turntable in the studio because they knew that's what people would expect to see if they talked about lemmings in their documentary-film.
Yes. It was called "White Wilderness". It featured a family of lemmings and documented its lives before pushing them off cliffs, stating that the population has grown too large, thus they are committing 'mass suicide'. Oh Disney, you maniacal, sinister, genocidal, freak you....
One misconceptions I heard about is that tarantulas' hairs sting you. Their hairs just bring on a very mild itch. On the note of tarantulas, their bites are only about as poisonous and painful as a honey bee
The lemmings misconception came from a documentary that was made about lemmings where the lemmings jumped off a cliff, most likely urged on in some way or another to run off by the presence of people who were desperate to get the documentary to be exciting.
The Lemmings-Story is invented by Disney. They made a documentary about them and thought Lemmings were boring. So they forced Lemmings into suicide, by chasing them up to the cliffs, where the small rhodents jumped off. They caught it on tape and invented this silly myth.
I guess that Lemmings misconception must have died off in the last nine years since I’ve literally never heard of a Lemming much less them being suicidal.
The reason people think that about lemmings is entirely clear. It was part of a Disney documentary where the director pushed the lemmings off a cliff to give the movie some excitement or something to that effect.
+bananian good things do come out of Disney, you just have to look for them lol, but they are pretty notorious for crap like this lol. Studio Ghibli all the way!
Fennekchu No, I mean't correcting him on how he said it. He said "Ghibli Stuido" I corrected with "Studio Ghibli". I have no clue about the Disney stuff. Xd
The source of the Lemmings myth is the 1958 Disney documentary White Wilderness. There they shoved dozens of lemmings off a cliff to drown claiming that they were "filled with a strong compulsion to migrate" which apparently wasn't stopped by natural obstacles like cliffs and the ocean. While they probably had gotten the idea from previous tall tales explaining the sudden crashes in the lemming population (which is caused by the periodic cycle of harsh and mild winters, harsh winters causing a population explosion because they have better snow cover to burrow through and be safe from predators while crashes result from mild winters causing lemmings to be exposed) they certainly introduced the idea to popular culture.
Disney can't be the "source" of the lemmings myth if they were repeating a pre-existing myth. Yes they helped _popularize_ the myth (and yes, they were jackasses for harming the lemmings), but they did not _originate_ the myth.
ostriches dig holes in the ground to lay their eggs in. whenever you see them checking or moving their eggs from a distance they look like they have their heads in the ground.
Hold on, people are going around saying Daddy Long Legs are venomous?! We used to have those in our house all the time and me and my sister would build little houses for them and stuff.
lemmings was because of a disney documentary showed footage. however what they didn't say was there were people on top of the cliff throwing the lemmings over the edge
Hopefully you've already discovered your misconception by now, but just in case: Disney did make a nature film for which they pushed lemmings off a cliff, but the myth did not originate with them. They pushed the lemmings off the cliff because they believed the pre-existing myth and wanted to film the phenomenon for their documentary.
I'm sure it's been said by now, but alas: there are different bugs called "daddy Long legs" (or a variant in spelling of those words) based mostly on region (think crayfish, crawfish, crawdad except they AREN'T the same things). What I call that are spiders and also venomous, but hardly so. I live in Alabama, where we have brown recluses, black widows, eastern diamondbacks, cottonmouths (aka water moccasin), coral snakes, king snakes, and copperheads; therefore we need to know what's venomous and what's not.
#5 is TRUE -- birds won't abandon a nestling because of the small of your hand! Put it back in the nest if you can. If not, LEAVE IT ALONE if it's covered with feathers! Lots of birds fall out of the nest a day or two early, they'll be ok, don't kidnap them from the parents. put them up in a bush or something. If it's a bare-ass baby and the feathers don't cover the skin, sure -- you can try to raise it but that's really hard.
It's best to return it to the nest. Raising the baby is 1) hard to do, since generally you need to feed it a lot of crickets and flies, 2) the bird might get imprinted on humans and never be truly wild or know where to find food in the wild, 3) for many birds it is illegal to keep them without a special license. I monitor blue bird nests (keep track of how many blue birds are hatched and raised), also run into tree swallows and wrens with this, and can say the parent birds don't care if you touch the hatchlings occasionally - but please don't bother them unless absolutely necessary!
MacNerfer Yes, excellent points and information! Everyone spread the word, put it back in the nest if possible. Lots of people still think the parents will reject it -- not true, (but it might be true for hamsters or mice?). I did nest monitoring some years ago, lots of species but focusing on willow flycatcher. Isn't it amazing how much you learn from that!
I love that you found AND USED images from the dinosaur cards that you remember from your childhood (that I would never have heard of, except that you discussed them with Brady. I'm older than you, but those cards must have fallen into the gap between being a kid and teaching kids.)
Do you mean venomous or poisonous on the daddy long legs segment at 0:29 because correct me if I’m wrong but venomous means if it bites you it hurts/kills you and poisonous means if you eat/bite it you get hurt/killed and if poisonous then they can’t even hurt you if you don’t hurt them
Daddy Long Legs absolutely are spiders in every way. Look up Pholcidae, or cellar spider. The misconception comes from people referring to crane flies (mosquito eaters) and harvestmen (nope bugs) as Daddy Long Legs. Pholcidae have both fangs and venom, and can bite a human (Mythbusters did a show about it), but their venom does not hurt humans. They are great to have around the house, as they kill more dangerous spiders that DO harm humans.
The cellar spider is a spider, yes. However, the many different interpretations of daddy-long legs gets in the way of having a clear-cut answer. The term 'daddy long leg' is associated with an arthropod with very long legs to a usually smaller body. This description makes it even more difficult to determine one, as the measure of 'big' and 'smaller' varies from person to person. Whether if a 'bug' is a daddy long leg depends on where you heard it, or which 'bug' was tied to the name.
Why do people say that ostriches stick heads in sand when in danger? How did that myth come to be? Is it maybe because that's how they search for food or something?
Ive heard in another video that ostriches soemtimes peck the heads of their prey in the ground to suffocate them. So it might have started from there if taht is true
I't may have come from the fact that ostriches remove dirt with their heads to make their nests, which may have looked like they were borrowing their heads.
***** Hate to reply to a comment so old, but since this is about another animal misconception I figured I'd make an exception. You know that saying that every person swallows X number of spiders per lifetime? Complete fiction, spiders, like most creatures that made it through evolution, avoid wandering into the mouths of other animals. They have extra incentives in fact; see since spiders like to walk around on surfaces like walls and ceilings they make sure to avoid surfaces that are too moist to walk up like they usually do (your mouth would be a surface they'd never take more than a single step into before leaving. Of course they wouldn't even get that far because spiders are also afraid of vibrations (yes seriously). Spiders have an extremely strong sense of touch that allows them to feel even small vibrations in surfaces which is how they get around; so when they encounter a strong/unknown vibration they generally want to get away from it (though there are some crazy aggressive species out there). A vibration such as breathing and especially snoring is enough for them to look elsewhere. In other words your even more lucky than you realized :D
Wait, hang on. Does the last one mean that if you take out a frog's brain but heat the water fast enough, it WILL jump out?
Actually, CGP got a bit lazy reporting this one. It's true that in 1869, Friedrich Goltz performed an experiment demonstrating that lobotomized frogs would not escape slowly-heated water but normal frogs would (and well before it got hot). However, follow-up studies by (Heinzmann 1872) and (Fratscher 1875) on intact frogs found that they would not jump out of water boiled sufficiently slowly, but would escape water heated quickly.

Chak Lee That's not quite right. Even cold-blooded animals like frogs maintain homeostasis, so they certainly feel the rising temperature. If their core temperature is too high, even if it is constant at that temperature, they will seek colder places. Apart from that, the temperature of the water will consistently be higher than the core temperature of the frog anyway.

(And the reason cold metal feels colder than cold wood is due to its much higher thermal diffusivity resulting in a truly colder temperature of the cold nerves in your skin. It is about heat transfer in this case, but only because the wood does not draw heat away from the nerves very quickly relative to the blood supplying heat, meaning the nerves don't get very cold. When you touch metal, the nerves do get cold. It's not just about how quickly the temperature changes. (Though rapid changes in temperature also do produce more obvious sensations than gradual ones, due to a separate mechanism.))
I'd say the question is moot: Are you going to get a creature like that to stay in the small pot period, boiling temperature or not?
LittleIslander If the pot is tall enough so the frog cannot jump out under any circumstances, then yes.

That's technically true (the best kind of true) But I've tried to find my brother in a room with a blindfold on, and it's really hard to find a moving person, because it's delayed due to the fact that you have to guess where the sound is coming from.
You aren't blind, so your brain hasnt adapted the processing power normally used for your sight into further audio processing. Think about it this way, our eyesight is superior to every other sense, so most of our sensory processing is for eyesight, without it, all that processing power goes straight to hearing and smell, making those senses far superior to a normal human
I once saw a documentary that showed a blind man who does this. What's interesting is that they also tested his preteen son, who _isn't_ blind, and he performed better than expected at acoustic wayfinding. Didn't verify any sources, so don't know how significant that is or what could've caused it, but it was interesting. In another documentary, a blind man actually demonstrated how accurate this skill can be, by drawing his surroundings based on what he sensed with his hearing as he traversed an outdoor area. He was able to tell when he was walking under a slatted roof, for instance. The accuracy of the drawing was impressive.

Didn't the Lemmings myth derive from an old Disney documentary where the film maker, controversially threw lemmings off the cliff? Correct me if I'm wrong - too lazy to google.
No, the film makers did that specifically because they had already heard the myth
+Indubitably This video was re uploaded with a section of that cut out, it talked about Disney for a sec but cant remember what it said.
+Indubitably actually yes. but he didnt throw them of, they were driven off the cliff. its a well known disney secret, it was also the very first nature documentary ever
I shit you not, in sixth grade we watched a documentary showing lemmings jumping off of a cliff into water.
+Neal Didriksen just read your comment, SO why the fuck would they show us that shit? I believed that for so long.
Daddy Long legs aren't spiders?!? Then wtf are they? "OK Google..."
I've actually looked this up in actual encyclopedias twice now. Daddy long legs are most certainly spiders, they are however NOT arachnids.
sorry strike that... reverse it. there ya go...
karn33333 Not necessarily. Here in Australia, it is the "cellar spider" which we call "Daddy Longlegs". So ours is an actual spider.
***** I'm sorry but thats wrong. a daddy long legs scientific name is Opiliones, while the cellar spider is a Pholcidae. One is a spider the other is not. the main differences is that a spider has two body masses the head and the abdomin are seperate, which you can see in Pholcidae but not in the Opiliones.
daddy long legs are also called harvestmen......"Harvestmen are an order of arachnids. Although they are often confused with spiders, the two orders are not closely related. Research on harvestman phylogeny is in a state of flux. While some families are clearly monophyletic, that is share a common ancestor, others are not, and the relationships between families are often not well understood."
karn33333 I know everything you just said. In Australia, the cellar spider is called a daddy long legs.
Turns out that in spite of what we thought for decades: that bats have amazing reflexes and use echolocation and their vision to gracefully avoid hitting other flying animals and generally...stuff, modern night vision cameras have shown... they hit stuff and other bats basically all the time.
2:30 this is a cuteness overload
the myth about ostriches cracks me up every time, those motherfuckers are violent, they are more likely to attack you than ever run away, even unprovoked they like being aggressive
Maybe the mother bird won't abandon their babies if you touch them, but one time we found a baby bird that had fallen out of it's nest, and for some strange reason, it imprinted (or at least took a very strong liking to us) and followed us around. The mother bird couldn't find the baby after it followed us for a while (despite our efforts to make it stay), and we found the bird dead from cold the next morning. :'(
That comment was so cute...till the shotgun to the chest ending there.
+Joseph Birch that's basically how you raise geese. Except you don't let them die from exposure of course, that's bad economics
+Alex Coffey Brutal
Maybe the mother had died and that's why its baby was unattended and could fall off
Maybe the mother had died and that's why its baby was unattended and could fall off
The main reason for the "Bats are blind" misconception is, while yes, they can see things, they are notably nearsighted, and use echolocation to make up for it.
If you boil the water slowly enough, the frog will starve to death/die of old age, and will therefore not jump out when the water gets too warm.
I re-watch all Grey’s early videos every few years! They are so great, just gotta remember to pace myself and not bin- ...crap did I just watch 12 in a row?!? 🙄
one kid used ecolocation and it workd but he was blind
I heard that but I get the impression it wasn't actually echolocation
people use echolocation every day
on submarines
and its called sonar
Matt D but we need maciens the kid maded the click noise himself
DailyLionGaming I get the impression thats not possible with human ears
impwarhamer Actually, it is. There was a teen named Ben Underwood. He became blind at a young age after having his eyes surgically removed. He was able to make a repetitive clicking noise with his mouth to use something similar to echolocation to make a map of where he was. People who lose a sense have their other senses enhanced, so it was possible that it was easier for him to hear the clicking than others. But the cancer that took his eyes came back, so he died recently :(
I thought lemmings suiciding was because of that old piece of film where they're jumping off a cliff. What is not shown is just off camera is a guy with a flamethrower. BTW that piece of film was funded by Disney.

+Robert Kuntzman The only difference is the delivery method. If you Eat them they technically are poisonous.
+Babylauncher3000 However, he was talking about the bite of spiders as seen a couple of seconds later when he debunked the myth that they can't bite because they have short fangs, because they aren't spiders. So when he said the myth that they were the most posionous spiders in the world, he meant the amount of poison they send through they're fangs which because they send it through their fangs they are in fact venomous. After all, all spiders are posionous if eaten and daddy longlegs are not spiders.
+Babylauncher3000 Not necessarily. Many venoms are only harmful if they get into the blood. The same substances could very well be harmless if eaten.
People think that lemmings are suicidal because one time Disney did a nature documentary where they literally pushed them off cliffs
I heard the frog thing about lobsters. the idea was they didn't have a central nervous system (or it was too primitive to detect boiling water) so it was totally OK to boil them alive. They couldn't feel the pain! I always thought it was a myth though.
It *is* true about oysters and many other molluscs, though - they have no pain receptors.
Munch KING the explanation I heard was that since they are cold blooded and can only sense temperature in relation to their internal temperature, if you raise it slowly enough they won't notice because their internal temperature will be the same as the external temperature.
Lobsters are bugs and as bugs don't have an analogous nerve cells to vertebrae pain receptors and therefore don't "suffer" from pain. They just react instinctively to stimuli. However, just bc they don't feel pain doesn't mean we shouldn't strive to keep the organisms making the ultimate sacrifice by feeding us as comfortable as possible. That's a good rule for society in general
@@fkrkf are all crustaceans bugs then?
Bugs isn't really a technical term but it does refer only to invertebrates so while crustaceans may have been around for longer and it might be more scientifically accurate to say bugs came from a crustacean lineage rather then all crustaceans are bugs, the word does the job of delineating the relationship between both terrestrial and oceanic arthropods. Unfortunately, as is common with colloquialisms, the term "bugs" also refers to creatures like slugs and snails and earthworms which are of a different and much older lineage then arthropods sooooo.......¯\_(ツ)_/¯
The Lemmings Myth was created by Disney with a documentary where they pushed Lemmings off the cliff and used the myth as an explanation.
Really? Or am I just gullible to believe you?
Yeah, Disney _actually did_ engage in this action, just to perpetuate an excuse for a myth.
@@claycandy53 can you elaborate
Perpetuated, yes. Created, no.

Toxic Atom more like 3 times the size, but yor point stands
chickens are actually direct descendants of velociraptors, because velociraptors were actually extremely small feathered animals
Didn't the "Lemmings are suicidal" myth start from some documentary where the makers deliberately drove the poor fellows off a cliff by scaring them until they did that?
It was a Disney documentary.After finding out about this and other things you probably won't see a Disney movie again and not think about these things.
Nope, it existed before then, that’s why Disney faked it

There was also a disney movie where the producers would throw the lemmings off of a cliff. That might be another cause.
I believe they only did that because the myth was already widespread - the directors couldn't find any lemmings jumping to their deaths in the wild to film, so they knocked them off a turntable in the studio because they knew that's what people would expect to see if they talked about lemmings in their documentary-film.
ChickenOfAwesome But the Disney movie theory is placed a few decades before the video game one.
黒い楓 Yeah, its pretty clear the game was based on the myth, not the other way around.
Yes. It was called "White Wilderness". It featured a family of lemmings and documented its lives before pushing them off cliffs, stating that the population has grown too large, thus they are committing 'mass suicide'. Oh Disney, you maniacal, sinister, genocidal, freak you....
"C'moooon Dinopocalypse!"
Haha, I love that line..!
One misconceptions I heard about is that tarantulas' hairs sting you. Their hairs just bring on a very mild itch. On the note of tarantulas, their bites are only about as poisonous and painful as a honey bee
The lemmings misconception came from a documentary that was made about lemmings where the lemmings jumped off a cliff, most likely urged on in some way or another to run off by the presence of people who were desperate to get the documentary to be exciting.
The Lemmings-Story is invented by Disney. They made a documentary about them and thought Lemmings were boring. So they forced Lemmings into suicide, by chasing them up to the cliffs, where the small rhodents jumped off. They caught it on tape and invented this silly myth.
damn, Disney is evil af!
Wrong. After chasing them down a cliff and seeing they wouldn't move, the director and the production crew personally started pushing them off
+SuperQuiMan That's fucked up.

Oh, I thought the lemmings were hardcore drugs from wolf of Wall Street 0_o
The reason people think that about lemmings is entirely clear. It was part of a Disney documentary where the director pushed the lemmings off a cliff to give the movie some excitement or something to that effect.
Your videos are just GORGEOUS.
The suicidal lemmings myth came from a 20th century Disney documentary about lemmings.

2:22 THEYRE SO CUTE
The bat one is really salty sounding and I love it
The source of the Lemmings myth is the 1958 Disney documentary White Wilderness. There they shoved dozens of lemmings off a cliff to drown claiming that they were "filled with a strong compulsion to migrate" which apparently wasn't stopped by natural obstacles like cliffs and the ocean.
While they probably had gotten the idea from previous tall tales explaining the sudden crashes in the lemming population (which is caused by the periodic cycle of harsh and mild winters, harsh winters causing a population explosion because they have better snow cover to burrow through and be safe from predators while crashes result from mild winters causing lemmings to be exposed) they certainly introduced the idea to popular culture.
Disney can't be the "source" of the lemmings myth if they were repeating a pre-existing myth.
Yes they helped _popularize_ the myth (and yes, they were jackasses for harming the lemmings), but they did not _originate_ the myth.
OMG this was besides very informative, also hilarious. The part about the bat especially, lol
Damn. That ending, tho. Savage.
ostriches dig holes in the ground to lay their eggs in. whenever you see them checking or moving their eggs from a distance they look like they have their heads in the ground.
The Lemmings were pushed off a cliff in some Disney produced zoological film back in the 60s
Hold on, people are going around saying Daddy Long Legs are venomous?!
We used to have those in our house all the time and me and my sister would build little houses for them and stuff.
Actually... when I think of Lemmings I think about either Disney telling us incorrect facts or small brown rodents eating lemons ;P
lemmings was because of a disney documentary showed footage. however what they didn't say was there were people on top of the cliff throwing the lemmings over the edge

The lemmings thing was started by a documentary where they pushed them off to get something to film.
Ostriches are the closest thing to raptors? Someone's never heard of a cassowary.
Imagine a red-green colorblind guy trying to find a red toy in green grass.
With his dog.
I heard the lemming myth was originated by Disney who threw a bunch of them off a cliff, then claiming that lemmings are suicidal.
Ok but why
Hopefully you've already discovered your misconception by now, but just in case:
Disney did make a nature film for which they pushed lemmings off a cliff, but the myth did not originate with them. They pushed the lemmings off the cliff because they believed the pre-existing myth and wanted to film the phenomenon for their documentary.
The frog in the thumbnail looks like he's ready to sit down and give me 'the talk'

I'm sure it's been said by now, but alas: there are different bugs called "daddy Long legs" (or a variant in spelling of those words) based mostly on region (think crayfish, crawfish, crawdad except they AREN'T the same things). What I call that are spiders and also venomous, but hardly so. I live in Alabama, where we have brown recluses, black widows, eastern diamondbacks, cottonmouths (aka water moccasin), coral snakes, king snakes, and copperheads; therefore we need to know what's venomous and what's not.
Love it! Please do more about misconceptions.
hahaha i love how someone, sometime failed to mention that the frogs brain was removed previously xD
#5 is TRUE -- birds won't abandon a nestling because of the small of your hand! Put it back in the nest if you can. If not, LEAVE IT ALONE if it's covered with feathers! Lots of birds fall out of the nest a day or two early, they'll be ok, don't kidnap them from the parents. put them up in a bush or something.
If it's a bare-ass baby and the feathers don't cover the skin, sure -- you can try to raise it but that's really hard.
It's best to return it to the nest. Raising the baby is 1) hard to do, since generally you need to feed it a lot of crickets and flies, 2) the bird might get imprinted on humans and never be truly wild or know where to find food in the wild, 3) for many birds it is illegal to keep them without a special license.
I monitor blue bird nests (keep track of how many blue birds are hatched and raised), also run into tree swallows and wrens with this, and can say the parent birds don't care if you touch the hatchlings occasionally - but please don't bother them unless absolutely necessary!
MacNerfer Yes, excellent points and information! Everyone spread the word, put it back in the nest if possible. Lots of people still think the parents will reject it -- not true, (but it might be true for hamsters or mice?).
I did nest monitoring some years ago, lots of species but focusing on willow flycatcher. Isn't it amazing how much you learn from that!
I accidentally put it on 0.5x instead of 0.25x to find something and grey sounded like a drunk robot! this is awesome!!
I love that you found AND USED images from the dinosaur cards that you remember from your childhood (that I would never have heard of, except that you discussed them with Brady. I'm older than you, but those cards must have fallen into the gap between being a kid and teaching kids.)
U forgot the one that chameleons don't change colour for camouflage but to indicate their mood.
Its both, isn’t it? Or am i just thinking of non-chameleon color changing lizards?
@@zombievac Out of the dozens if not hundreds of chamelion species, only two change color to camouflage.
Do you mean venomous or poisonous on the daddy long legs segment at 0:29 because correct me if I’m wrong but venomous means if it bites you it hurts/kills you and poisonous means if you eat/bite it you get hurt/killed and if poisonous then they can’t even hurt you if you don’t hurt them
That frog in the thumbnail is adorable, and I have to dissect a frog tomorrow...
That was pretty entertaining, I'm glad I found your channel.
Daddy Long Legs absolutely are spiders in every way. Look up Pholcidae, or cellar spider. The misconception comes from people referring to crane flies (mosquito eaters) and harvestmen (nope bugs) as Daddy Long Legs. Pholcidae have both fangs and venom, and can bite a human (Mythbusters did a show about it), but their venom does not hurt humans. They are great to have around the house, as they kill more dangerous spiders that DO harm humans.
The cellar spider is a spider, yes. However, the many different interpretations of daddy-long legs gets in the way of having a clear-cut answer.
The term 'daddy long leg' is associated with an arthropod with very long legs to a usually smaller body. This description makes it even more difficult to determine one, as the measure of 'big' and 'smaller' varies from person to person.
Whether if a 'bug' is a daddy long leg depends on where you heard it, or which 'bug' was tied to the name.
Don't they have 10 legs?
Why do people say that ostriches stick heads in sand when in danger? How did that myth come to be? Is it maybe because that's how they search for food or something?
It is. In fact, Ostriches will actively choose to charge at someone shooting at them.
Ive heard in another video that ostriches soemtimes peck the heads of their prey in the ground to suffocate them. So it might have started from there if taht is true
PowerShot Spaz Damn, ostriches are brutal. :(
I't may have come from the fact that ostriches remove dirt with their heads to make their nests, which may have looked like they were borrowing their heads.

Woke up with 2 large spiders in my mouth last night. FML
I hope this never happens to me.
***** I would piss myself if that ever happened to me. And it's very likely too since I live in a house with a lot of spiders.
***** Hate to reply to a comment so old, but since this is about another animal misconception I figured I'd make an exception. You know that saying that every person swallows X number of spiders per lifetime? Complete fiction, spiders, like most creatures that made it through evolution, avoid wandering into the mouths of other animals. They have extra incentives in fact; see since spiders like to walk around on surfaces like walls and ceilings they make sure to avoid surfaces that are too moist to walk up like they usually do (your mouth would be a surface they'd never take more than a single step into before leaving. Of course they wouldn't even get that far because spiders are also afraid of vibrations (yes seriously). Spiders have an extremely strong sense of touch that allows them to feel even small vibrations in surfaces which is how they get around; so when they encounter a strong/unknown vibration they generally want to get away from it (though there are some crazy aggressive species out there). A vibration such as breathing and especially snoring is enough for them to look elsewhere.
In other words your even more lucky than you realized :D
