Call of the Wood Frog (Lithobates sylvaticus)
Fun facts: Wood frogs are well suited to a cold climate. They spend winters burrowed in the leaves that fell the previous fall. They stop breathing, their hearts stop beating, and ice crystals form within their hibernating bodies. A special antifreeze they produce keeps liquids from freezing inside their cells and killing them. Their fertilized eggs are not harmed by freezing either. Egg development simply stops until the water warms again. The wood frog is the only frog found north of the Arctic Circle.
Another fun fact: wood frog tadpoles can tell their brothers and sisters from other tadpoles.
