Rana catesbeianus

Bullfrog (Rana catesbeianus)

Where found: The American Bull Frog is native to North America. They are found in the United States, Canada and Mexico, east of the Rocky Mountains, but have been introduced to many other localities throughout the world. In Europe and the western U.S., measures are often taken to control its spread because it competes with, and often drives out, native species.

Description: The bull frog is a large species that has many similarities to its 'sister species' of toad, and can grow to a length of 6 inches (15 cm) with a weight of up to 1.5 lb (750 g). Females are typically larger than males. They are generally varying shades of green or brown, with dark brown, dark green, or black blotching and a yellow or white underside. Bull frogs are carnivorous and will consume almost anything that fits into their mouth which they can overpower, including insects, small mammals, fish, snakes, and even other frogs. They tend to eat more dragonflies than flies. The adult frog can live up to 13 years.
