American Bullfrog (Lithobates catesbeianus) is another invasive species.  It is a member of the true frog family, Ranidae. It is native to the eastern half of the United States. They are usually around 3.6 to 6 in (9 to 15 cm) from snout to vent.

The bullfrog eats anything that it can fit into its mouth, allowing it to eat snakes, birds, other frogs, and other animals. This can lead to decrease in population sizes of other animals and could lead to extinction.  In California, the bullfrog has decreased the populations of the native California Red Legged Frog.

Bullfrogs have been brought all over the world as a food source. They are purposely released into the wild or escape from frog farms.
