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.

It can remain in this state for months, making it one of the few amphibians that can survive in the cruel winter cold.
