American Bullfrog
Large and aggressive North American frog
The American bullfrog (Lithobates catesbeianus) is one of the largest frog species in North America. It can grow up to 15–20 cm in body length and is an aggressive predator. Its diet includes insects, small fish, birds, and even other frogs. Because of its adaptability, it has become an invasive species in many regions outside its native range. Bullfrogs produce a deep “jug-o-rum” call that can be heard from a distance. Their large size and appetite make them dominant in aquatic ecosystems.
