[QUOTE="GoingNorth, post: 332686, member: 1963"] There are a very few types of Arctic fish and crawlies that can survive extreme cold. They have a sort of antifreeze mixed in the blood that protects cell walls. Otherwise, true freezing breaks down cell walls due to water crystals forming in the cells. A LOT of snakes can hibernate, which for them is extreme torpidity. Metabolism slows to nearly a standstill. Alligators are more cold tolerant due to their physiology, but they cannot survive freezing conditions for any length of time either. [/QUOTE]
