eli5…How do wild mammals not freeze to death

Deer, foxes, rabbits, etc. are all warm blooded mammals that regularly experience sub-freezing temperatures that would kill humans in a matter of hours. How do they survive?

Deer have thin legs that are pretty much all tendons and bone. So… Their legs do kind of freeze. But because it’s soo thin and their bodies are compact and insulated they can keep the thin amount of blood flowing through the veins thawed out enough.

Also. Once it’s below 20, dry snow becomes a very very good insulator.

Just last night I had to get something from my truck late at night and I just went out in my socks. It wasn’t cold on the feet at all because the snow doesn’t melt.

Felt like walking on styrofoam.
