The Wood Frog, Rana sylvatica, exist from Alaska, through Canada, and down through the eastern United States.
The Wood Frog has an amazing ability to withstand freezing temperatures. They can even survive having their blood, and body tissues frozen.
Wood Frogs reach a size of a little less than 3 inches as adults. They occur in a range of brown colors, and in most cases have a darker colored eye mask.
