Bullfrog. Young North American bullfrog (Rana catesbeiana) eating a worm. This frog is found throughout North America near lakes, rivers and marshes. This is a young frog. When fully grown it may reach a length of almost 50 centimetres, making it the largest frog in North America. As well as worms, bullfrogs eat snakes, insects, crustaceans and even other bullfrogs. They are known for the males' rumbling calls, which can be heard for over a kilometre. Males are territorial and defend their stretch of river or lake shore with considerable aggression.
