Bullfrog

frog

Bullfrog, large North American frog (Rana catesbeiana) named for its booming call, which is made by passing air up and down the windpipe, the swollen airsacs acting as resonators. Bullfrogs grow up to 8 in (20 cm) long and live near water, where they feed on many kinds of animals, including small snakes and alligators. They hibernate under logs or in holes, emerging in spring to lay up to 25,000 eggs.
