> Alligators can survive Tennessee winters by going into a hibernation-like dormancy called brumation. They can withstand periods of ice by sticking their snout out of the water before it freezes which allows them to continue breathing. <
Amazing. If they're sticking their snout above the water surface, that presupposes the rest of their body is under water, but that the surface is beginning to ice up. Before water gets to 32F, it has to go down through 40F, 38F, 36F, and so on. And as the surface freezes, one would expect the rest of the still liquid water underneath to be only a degree or two warmer. That presents a picture of a gator fully immersed in, what, 35F or 36F water? Can they take that? And is cold-blooded REALLY cold-blooded? Do gators' body temperatures reflect the surrounding temperature? Can a gator be, say, 38F all the way throughout it and still be alive?
So many questions.
