Characteristics of American Bullfrog
The American Bullfrog possesses several distinctive characteristics:
- Size: One of the largest frogs in North America, reaching up to 8 inches (20 cm) in body length.
- Color: Typically green or brown with dark blotches on the back and a lighter underside.
- Sound: Known for its deep, resonant croak, which can be heard over long distances.
- Diet: Carnivorous, feeding on insects, small fish, other frogs, and even small mammals and birds.
