Frog

Frogs are tailless amphibians with strong hind legs and bodies suited to jumping, swimming or climbing, depending on the species. Most adults feed on small animals. Many begin life as aquatic tadpoles, although some species develop without a free-swimming larval stage. Moist skin can contribute to breathing, making suitable shelter and humidity important. Calls are often used to attract mates or mark space. Species range from ground-dwelling and burrowing forms to tree frogs with specialized climbing pads.
