FREEZE TOLERANCE: WHY DO NOT ANIMALS BECOME ICE DURING WINTER?

Some animal species have a body temperature that fluctuates with the temperature in their surroundings, unlike humans who must stay around 37°C. The great thing about this is that they do not need a lot of energy to heat their bodies. The bad thing is that they can become too hot or too cold for their cells to function well. In Arctic and other cold environments, these animals have developed amazing adaptations to avoid that their body fluids freeze. Some actually allow ice to form in their bodies, but survive nonetheless. In this seminar, you will learn how they are able to avoid “death by freezing”.
