Pictures of wood frogs, brown/tan frogs native to the northeastern United States and Canada. Wood frogs are also known as "the frog with the robber's mask", because of the dark patch that extends from their nose and across their eye.
Wood Frogs range from 1.5 to 3.25 inches in length, and females are much larger than males. Wood frogs are interesting because they're capable of freezing completely solid to survive the Winter. The frog generates a form of antifreeze to keep vital components from freezing, and then slowly stops its lungs, heart, and brain activity. After the Winter, in as long as three to five months, the frog thaws out and hops away. Wood frogs eat snails, slugs, moth larvae, spiders, and beetles.
