makes me happy knowing the Terrapin's at my local lake are doing well :)
I don’t wanna know how they tested how long these animals can freeze without dying
69 dislikes, no one dislike this video.
I’ve found these frogs back home in Alaska as a kid. Always weirded me out because I Knew they were going to come back to life one. I didn’t even know we had frogs in Alaska until I found one frozen 😂
I’ve always been fascinated how turtles and frogs can survive the harsh winters up here in Minnesota.
Seems like being suspended in animation maybe harder to come back from rather than cryogenic...
Gators stick their snouts out of the water and hibernate if it gets could enough to freeze the swamp.
So glad you decided to let us see both your eyes again.
Woah! I guess I wasnt aware of how powerful Squirtle is. I seriously underestimated Squirtle my whole life! Now I regret not picking Squirtle as my starter from Proessor Oak.
Did he say ex-turtle heat sources?
Apparently there's also a moth that lives in one of the arctics that freezes until like the two weeks of spring and feeds during the short spring and then freezes over again until it has enough energy to become a moth and then it dies off but it can live about 40 years 20 to 40 years depending I think
Dude called ice a crystal structure. Sir hank green has confirmed ice is a rock on tiktok
please please please also show Fahrenheit, inches, feet, mph etc.... for us folks over 40. thank you....
Useful for Mars, too.
I just realized that those wood frogs that freeze are the ones in Avatar the last airbender when Sokka and Katara were sick. I wonder if they really due cure flu when you suck on them while frozen lol
O Micheal.. How i miss ur colorful hair😛😊😊
dude michael's hair looks amazing lol
sad that Michael was not wearing his jacket/vest
" evolution really thought of every thing" I'm sorry but that's a very stupid statement , not only evolution theories isn't a fact but also non of it as far as I know suggest evolution having a mind of its own
So mind some "winterhard" vegetables like some salads or birch trees that could had prepared some natural form of chemical stuff humans use to prevent freezing
Turtles be like: But wait, there’s more...
I never thought about what turtles do for winter. I figured they hibernated until it got warmer.
Why isn't there a single comment about the frozen wood frogs in the episode of Avatar the Last Airbender? Come on guys!
3:05 frogs make blood ice cream.
Snake discovery just did the video on the painted turtles and the frozen pond
...how did the turtles "figure out how to breathe water through their skin" ?? Seeing that science could safely say they did, how did they actually? Evolution..the end?
Good one
They was a woman that died and froze for like a week that came back somehow
I'd like to know how cold-blooded animals can remain active in cold conditions. For instance, here in San Diego we have lizards, which are only active when the weather is warm. But we also have salamanders, which seem to be most active in cold weather only come out at night and are most active in cold weather. How do the salamanders thrive in conditions that would put lizards into torpor?
@Simon Jäkle well it depends on what you think of "on its own". It is selected through millions of years of evolution, so you can have stuff living in almost any part of the planet, even in boiling water.
@Ron Wesilen does that kinda happen on it own?
Different enzymes (the proteins that make the chemical reactions inside your body) work better at different temperatures, so just use the ones adapted to your temperatures
The Axolotl as well as coast stars (sea star) can regrow recent parts of their body, like some crab animals get a new "scissor" when that part gets lost. some scorpions survive "almost everything", some bugs can stay in rooms through the entire cold season seemingly eating nothing, snails can sleep for three years and that list of tough life'd go on i guess. It's "us the humans" that are the weakest link.
The salamanders would be nocturnal because of the lizards, to avoid competition. As for how they're nocturnal, they've probably adapted to not need as high of a body temp to be active. Having a body even a few degrees cooler can make a lot of difference.
What a powerful scientific theory is evolution! Charles Darwin was a genius. Natural selection, mutation, genetic shift, antigenic drift, and gene flow (migration)-these mechanisms of evolution are used even by viruses. Look at the coronavirus (COVID-19)! Scientists worldwide are successfully developing vaccines but this virus is constantly mutating. Evolution before our very eyes! 💕 ☮ 🌎 🌌
So is this what happened to Han Solo when Vader and the Emperor carbon froze him in Empire Strikes Back (episode 5 to all you millennials)? Hmm, interesting
Weather: “Winter is here, baby!” Invertebrates: “Guess I’ll-“ Weather: “die?” Invertebrates: “No, freeze. Wake me when it’s spring. 🥱”
Real Science made a video about this 4 days ago. Coincidence? Probably.
Fascinating
I have a red-eared slider. It lives in a small pond during the warm seasons and during winter it actually burrows underground. I didn't know they could do that.
Oh, turtles put themselves in slowmo? Shocker.
0:11 that is definitely a missed chance to make a pun with turtlenecks
Im suprised this video didn't mention Alligators who stick their noses out of ponds when winter freezes over.
I never cease to be amazed by these creatures, truly spectacular!!!
Glad you guys are doing other videos again i stopped watching cause for a while it was just Hank and Covid. That was wack
As I learned from RPGs the more of an element a critter has the more elemental damage and resistance it will have to that element. So I would expect cold blooded animals to be frost resistant and to deal frost damage.
who else thought avatar when he was talking about frozen frogs?
Good to see you getting back in shape
I used to dislike anytime it wasn't Hank teaching a SciShow but now I like just about all of the hosts.
Question, what exactly makes an animal cold blooded or warm blooded. What mechanism is at play to distinguish the twin from one another
Turtles breath through the skin in their butts! Info a la snake discovery
QUESTION. Related to this video's subject. How do 'cold-blooded' fish remain constantly very active in temperatures that reptiles can't function at all in?
oh thank god! the mullet is gone
Ok, it's clear that we are going to be invaded by alien super frogs that could survive the long space travel.
I wonder if that frog tastes sweet
So frogs strategy for surviving freeze is to get diabetes 🤔
I'm clearly lacking in the cold survival front
One of the best hosts.
Utterly fascinating.
Dang nematodes....
2:07 the most stupid statement in your whole life.
2:08 Not EVOLUTION but GOD
Us humans can unlock cold blooded by being a sociopath. *T H A N K S F O R T H E A D V I C E*
Wow super cool episode guys
If we knew how we are born on earth then why religion comes? Any answer to scishow?
i wish you would've mentioned the frozen crocs
That is insane
Cells get destroyed by. freezing??? Sounds like a great way to target and kill cancer cells 🤔
0:42 Staffelung
I thought painted and snapping could defuse in oxygen and co2 out through their cloaca in winter months it’s called cloacal respiration
This is how we get to Buck Rogers & Captain America , Dylan Hunt, Ripley, Khan , Frankenstein's Monster, and Woody Allen.
Real Science released a video on the topic 2 days ago. Coincidence? I think not.
I love that you mention wood frogs. I love these little guys. They come out every springtime thaw and ribbit up a storm, you can hear them for miles. They eat all the mosquito larvae. And then the cranes come and eat all the frogs.
0:26 Bernie Mittens
Isn't that cryonic, not cryogenic?
My tortoise didn’t come up with any brilliant ways to survive in the cold when it got out in the winter
Some turtles, when under frozen ice in low oxygen environments, use a special method of breathing to extract extra oxygen. It's called cloacal breathing. It's as gross as it sounds.
You need a haircut
Crab Check: No. There were no crabs in this video.
😀
Joking aside, wouldn't a sweater on a turtle still work? Part of what makes us warm blooded is our insulating fat which traps the heat our body makes. So doesn't a turtle also generate heat just by moving around? So wouldn't a sweater still capture this?
wow, I mean WOW!
they need no ice and a temperature difference that is higher than the colder part, kinda sorta a little bit.
Looks like someone at scishow saw real science’s video and decided to rip it off.
How do the Wood Frogs avoid diabetes?
Does sucking on frozen frogs cure a cold you got from helping a stubborn fisherman in a hurricane?
If your cold-blooded and the weather is cold, then you cannot be cold.
But can you suck on the frozen wood frogs?
The actual question about the freezing frogs is less how they manage to not get their cells damaged by freezing, but what makes their hearts start again out of nothing after having defrosted.
FBC14 algorithm is the best, there is no point in arguing with this
Are you guys idiots? There is FBC14 algorithm!
Author, the best thing you can do is to invest in FBC14 algorithm and dont worry about rates
Pray for FBC14 algorithm!
Guys, you are tired, before doing reviews, you first read about FBC14 algorithm
FBC14 algorithm is the best cryptocurrency investment in my life
FBC14 algorithm is my choice, i dont worry about BTC rates at all
Why review cryptocurrencies if FBC14 algorithm wins everyone?
Nice video! What about FBC14 algorithm review?
Nice try, but read about FBC14 algorithm first
is there really still a person who does not know about the existence of FBC14 algorithm?
LOL FBC14 algorithm everywhere
FBC14 algorithm everywhere
Thanks i knew about Michael Hill! He was my professor in Oxford and told us about FBC14 algorithm!
Why watch all these quotes!? Read about FBC14 algorithm
