Tadpole of American bullfrog, Rana catesbeiana. About the time the front legs emerge, the small round mouth of the tadpole widens and transforms into that of an adult frog. Native to the Eastern United States, bullfrogs were introduced and have become established west of the Rockies. Bullfrogs are large, aggressive predators and prolific breeders, and have seriously depleted native frog populations in many areas of the West.
