Question

During the winter, many species of amphibians and reptiles go into a hibernation-like state called overwintering. They eat little or no food, slow their metabolism and breathing rate dramatically, and most of their bodily functions shut down. Interestingly, many of these species choose to spend the winter underwater. Why might it be advantageous to overwinter at the bottom of a pond rather than on land?

Answer 1

Water has a high specific heat, so the pond water under the ice is warmer than the outside air
