The Wood Frog The wood frog is not an ordinary frog. When winter arrives and the temperatures drop, the wood frog's body freezes. However, this frog does not die. The wood frog has incredible features that allow it to live through the winter. The wood frog's body contains special proteins that freeze the water in its blood and cells. A special solution that works much like antifreeze in a car protects the frog's cells. A wood frog can survive when the temperature is as low as 20 degrees. Amazingly, the cold does not damage the frog's body or organs. When the warm weather of spring arrives, the frog thaws. Within several hours of defrosting, the frog's organs and muscles begin operating again. The wood frog can hop, eat, and swim as usual. These unusual frogs live in Alaska and in many parts of Canada, where their natural defense to cold temperatures comes in handy.
