The American bullfrog, named for its loud, deep mating call, eats insects, fish, birds, snakes, baby turtles, and other frogs. Bullfrogs are native to the eastern U.S., but they have been released west of the Rocky Mountains where they have devastated local populations of frogs and other small animals. The eight species in this slideshow are among the 18 species frogs from around the world on display at the exhibit 'Frogs: A Chorus of Colors,' which runs at the Museum of Science, Boston, from February 13 through May 25.
