Hi Lauren,
I appreciate the input.
While I'm not saying you're wrong, let me point out that Wood Frogs will use the thinnest cover in winter and allow themselves to freeze solid. They are then capable of "re-animating" in spring. In this case the frogs are certainly not trying to stay warm, but are in fact allowing themselves to reach extremely cold temps. So the matter can be fairly complicated. So in your case are the toads "trying to stay warm", or are they "trying to stay cold"?
Some turtles seek out water that won't freeze but is very cold and allow their metabolism to slow down so much that they do without normal breathing for the duration of winter. (There may some gas exchange in their throats and/or cloacae, but no lung respiration.)
I am glad to see people thinking. That is always a good thing.
So, Lauren, I don't know if you're right, but keep exercising your brain.
