These frogs are amazing at surviving the coldness of winter. They are able to freeze and thaw out with their surroundings with little damage to their body. Researchers are studying how they can use this technique for organ transplants to preserve human organs for longer time without damage. Wood frogs are distinguishable by the raccoon-like mask on their face.
