The bull frog is the largest frog in North America, reaching lengths of 6 to 8 inches. Itâs a brownish-green color with dark colored bands or blotches on its hind legs. Unlike the treefrogs, the bull frog has webbed hind feet. Theyâre often found near permanent waters with lots of vegetation. This species size and carnivorous diet allows it to munch on creatures such as snakes, bats, ducklings and other frogs! Behind the bull frogâs eyes are eardrums known as tympanic membranes. The size of these membranes can be used to determine if the frog is a male, itâs larger than the eye, or a female, the membrane is the same size as the eye.
