Frogs have slender bodies with long, powerful hind legs, short front legs, and webbed feet. They develop from
tadpoles, and most species when fully grown can live in water or on land. Their skin is smooth. They are
excellent jumpers and swimmers.
Toads have short, thick bodies and short legs. The toad's skin is dry and has a rough appearance. True
toads have skin glands that produce a poison, which can be very irritating to the mucous membranes of predatory
animals. Most live on land in and around moist areas.
