The Wood Frog
Things that might eat you aren’t always the most fearsome predators. In many cases it’s the weather itself that will do you in. Well, the North American wood frog has the amazing ability to come back to life after being COMPLETELY FROZEN. Its brain and heart activity ceases and goes into a state of reanimation due to the fact that its liver secretes tremendous amounts of glucose, which acts as an antifreeze. It can remain in this state for months, making it one of the few amphibians that can survive in the cruel winter cold.
