THANK YOU! This episode, and many others, are riddled with scientific inaccuracies. That bugs me HARD because SciShow passes themselves off as all scientific and whatnot… but actually has a lot of errors. See my other comment on this vid as an example.
Also, it’s just basic scientific Latin that every actual scientist of any sort should have down pat. Any real scientist should know in their sleep that the prefix auto- pretty much means self, and the suffix -tomy mean cutting or incising (e.g. vasecTOMY or hystecTOMY, etc.) Any actual scientist should reflexively known that “autonomy” is incorrect! It’s embarrassing.
@@FeralMina this literally isn't a scientist. It's an entertainer reading a script lol. Sci show always corrects their mistakes and thanks people for pointing them out. Autonomy vs autotomy is not that big of a deal lol.
I once kept a cockroach inside a bottle just to see how long it can survive without food and water...it amputated it's right middle leg and ate it. That's probably the first observed self amputation followed by self cannibalism. I didn't know then that the cockroach leg can grow back. This one however didn't as it died after around 18 days.
The word is AUTOTOMY....auto- "self" and tomy-"cutting". Autonomy refers to independent decision making and action....c'mon, SciShow.....You're better than this!!
autotomy or self-amputation...what's wrong with using the more descriptive word instead of the more sciencey one? SciShow caters more to the normal viewers. Using the word once or twice would've been better though but self-amputation is just as good.
I used to raise crickets and katydids. They sometimes lost back legs, especially while molting. I think they got stuck in the exoskeleton if the terrarium was too dry and chose to leave the stuck leg behind. I didn't realize that they were removing the legs on purpose, though.
Doesn't anyone think that the following statement is misleading?: "The slugs incorporate algal cells responsible for photosynthesis, known as chloroplasts, into their own cells". It gives the impression that chloroplasts are algal cells instead of organelles of algal cells. And no, they are not complete and self functional Cyanobacteria in this case to make both the cells and the chloroplasts somehow equivalent.
According to a paper I recently eyed through (Christa, Gregor et al, Plastid-bearing sea slugs fix CO2 in the light but do not require photosynthesis to survive) the slugs do not photosynthesize, but use them as a food reserve.
Everyone on here is annoyed that they said autonomy instead of autotomy; but I’m annoyed that they didn’t even mention the creature that perhaps does this most impressively. The starfish
If you grab a species of harvestman, such as a daddy long legs be a leg, there's a chance they'll just relieve the pressure on the joint section and detach the limb leaving a small blob of goo to encompass the gap until it permanently closes in on itself. They can do it with just about any leg, and you'll probably see a few roaming around without a leg or two, I know I have.
You don't know where the food goes in the bodyless slug? Imagine some scp thing where the slug still behaves as if it were still together and the food just appears in its body after the severed head eats it.
Not all nudibranchs eat algae. Some are predatory and eat corals as well as other animals. The ones that only eat algae are extremely popular in the reeding community while the others are obviously not.
There's these funny little ants that are born with wings, fly away from home, then they'll rip them off and start walking around. It was very cool to see
Those are probably new queens! More info, if curious: In many ant species, the reproductive members (called alates) are winged and wait inside the colony until the conditions are just right for their nuptial flight. All the alates from different colonies take to the skies at the same time to mate, then the males die shortly after. Newly fertilized queens, however, will usually remove their own wings and begin the process of finding a good spot to found a colony. In a lot of species, she will seal herself away with her first round of eggs and her body will use the now useless wing muscles as fuel until these initial offspring are old enough to go out and find food for her. I recommend watching videos from AntsCanada if you’re at all interested in learning more! He makes antkeeping way more interesting than it has any right to be.
Pretty sure that’s in every ant? Fertile males and females are born with wings so they can fly away from the colony they were born in, mate, and establish a new colony (well, the female does that last part. The male dies, I’m pretty sure). And after they’ve done that, well they don’t need the wings anymore, so they’re just a waste of nutrients. This, ripping off the wings
Am I the only one that saw the title of this video and thought: "I will bite off my own leg to get get away from you!" I can't be the only one that thought about that situation.
I mean as far as the cactus bug thing goes, we did the same exact thing quite frequently as recently as the 1800s (and still do, in some scenarios). They aren't really special there, beyond having a built-in breakage point. We just grabbed the nearest saw and got to work
I'm not sure if there's a place to suggest this, but could you guys do an episode about vanishing twin syndrome, superfecundation, chimeras, and other strange things that happen in the womb, and specifically what are the chances of these things? I'm curious cause I started doing minimal research about how a baby might have two dads, and apparently, it's basically just fraternal twins, superfecundation, vanishing twin syndrome, surviving twin absorbs the dead twin, baby, and I'm very curious about what are the chances of something like that happening.
I believe there's a kind of cave dwelling cricket that will actually *eat* one of it's own limbs if it has to go a particularly long time without finding any other food. As you've likely guessed, said limb doesn't grow back.
This video might be worth reposting, just to correct 'autonomy' to the correct word, 'autotomy.' It's important to get your terminology correct if the aim is to educate.
I'd have loved to see y'all cover that most lizards do not regrow tails in adulthood and so this is a one-time last resort, but also about sea-stars because those can get HELLA WILD. "One and a half leg? Meh, good enough for now."
• 0:20 - Um, it's not autonomy, that means independence. It's called AUTOTOMY. 🤦 • 2:23 - The slug didn't discard its head, it discard its body. This isn't even a philosophical matter of which is the original/real slug because the severed head grew a new body but the severed body died. (Incidentally, the guillotine wouldn't chop people's heads off, it would chop their bodies off.)
Been keeping tarantulas for years, and when feeding them a cricket, you have to grab them by the body. If you pick them up with tongs by a leg, they'll almost immediately start to chew it off.
Thank you to everyone who pointed out our mistake! Yes! The process of ditching a body part on purpose is known as autotomy, not autonomy!
