Male frogs have vocal sacs on either side of the throat. These act to amplify wounds. Some frogs and toads even sing in chorus. Frogs and toads have a strong sense of location. When taken from their territories or breeding grounds, they can find their way back by smell and instictively by the position of the stars.
Many migratory species tend to return to the same breeding grounds year after year.
Amphibians respond to danger in several ways. Some dive in the water or hide in dens. Others pretend to be dead or camouflage themselves by changing color. Others protect themselves with poisonous skin secretions, or puff up to look large and frightening. The enemies of amphibians include foxes, hedgehogs, storks, herons, snakes, and large spiders.
