My favorite realisation was that cold and warm blooded creatures are different forms of efficient. Enzymes are pretty temperature dependent so warm blooded creatures can get by with a "small" set but then have to control their temperature. On the other hand, cold blooded creatures don't need to spend energy to maintain a stable temperature but instead need to have a much larger selection of enzymes available for different temperatures.
Wood frogs are actually pretty cool. Other than freezing over winter when they croak they sound like ducks. They are found in vernal forest pools in early spring where they lay their eggs. When the vernal pools dry up the frogs are turned out to live the rest of the year in the forest. I love wood frogs and painted turtles.

depends on the species and area, but most snakes enter burmation. it's kinda like a semi-hibernation. hunker down somewhere to keep as warm as possible, sleep often and slow metabolism to as low as possible while burning just enough fat to stay above freezing, but if a warm front of particularly warm day hits they're still awake enough to slither right out and hunt/sun themselves real quick before hunkering down.

You always wondered about something and never took the time to google it?? Im calling shenanigans.. You just wanted attention for ur bday. Happybirthday
Very true, but it makes you wonder. If individual cells are mostly the same, why do humans die when their core tempature gets only a few degrees colder but other animals don't? Like what do those few degrees actually do? We're weird creatures.
@@zaptowee6625 DNA. Sure Eukaryotic cells have similar physiology, but the proteins produced through differing genes makes all the difference. When one cell is capable of making a protein with enzymatic functions that efficiently breaks active groups off of, let's say, botulinum toxin, then that cell effectively becomes immune to that substance's I'll effects. It's a similar idea for surviving just about anything. Proteins are responsible for *that* much in the cell. This person made a movie reference, so why are we discussing the complexities of life in their reply section?
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?
Mis-interpretate me but look at some viruses, more than half of them will have found a symbiotic way to live among "higher" animals, like herpes. Those tiny "objects" are like zombie, and some people'd say "we" share 5 to 8 percent of the "genes" with them, so if there's some zombie stuff lurking in dark-angled part of some mammals. If one has ways to relate to dead (but) moving stuff
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.
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.
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
If anyone is curious about the painted turtles, snake discovery recently put up a video about it with footage they found of turtles actually in those frozen ponds
There is a natural spring lake near my house that is always warm no matter the temperature. It is always 70+ degrees even if there is snow on the ground. :) I love watching the steam rise up from the water when it is cold. Lots of turtles, frogs, fish, plants and other creatures live there too and because of protections are the only ones that can swim in it. :D - Heidi
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.
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.
My dad at one point was digging a hole in the dead of winter in the American Midwest and found several dozen snakes cuddled up together in a tight-packed ball.
I think they can only survive the freezing temperatures if they desiccate into a tun before doing it, they dont really survive the ice in their cells as far as I know
You mentioned that being cold is uncomfortable for humans because we are warm blooded. Would you ever do an ep on Reynaud's disorder? To my knowledge it is a circulation issue, I have it myself. It makes it painful to be chilly and causes fingers and toes to go numb and change color even from AC cooling. How does it actually work?
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.
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
I heard fish could be frozen and brought back to life when I was a kid. My mom wouldn’t let me try the experiment. Nematodes scare me a little. One of the first things you study as a biologist. They are not like other living things. They are different.
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.
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 😂
If you're trying to freeze your self for a Nintendo Wii, be warned, you can end up in a time where it becomes an ancient technology. Then you have got to deal with talking otters.
Carrots and parsnips avoid freezing just like those frogs, by sugar infusing their cells. Which is why they taste so much better after they've survived some cold. Hmm, I wonder...
What about Water Bears/Tardigrade surly they can be frozen many times as well as Nematode worms without harm as they can push all the water out of their bodies.
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?
Es gibt auch Reptilien die bei tiefen Temperaturen noch funktionieren es gibt aber nur wenige davon. Verdauen geht ab 10 Grad. Bewegung schon mit 1 Grad beispielsweise kreuzotter.
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

So that's where the ducks go during the winter! (Guess the reference) :D
