Garter snakes and generating heat...

[Zephyr]

Well, there hasn't been an experiment on it, so I'm thinking I'm going to go ahead and try it. There has to be another reason why they can tolerate cold and emerge from their dens before other species of snakes. I mean, there's exceptions to everything. Take leatherback seaturtles and tuna! I know there's a difference in environments, but both of those species can generate heat and are from so-called "cold-blooded" orders!

There are garter snakes observed that were active when there still was snow.

Which would mean they have a high tolerance for cold or they can, at times, generate their own body heat.
Both of which would be interesting finds.

The fact that they can tolerate very low temperatures has been known forever.... They can't generate their own heat internally. No more than I can lay eggs.
