FROG Frog is a small, tailless animal with bulging eyes. Almost all frogs also have long back legs. The strong hind legs enable a frog to leap distances far greater than the length of its body.
Frogs live on every continent except Antarctica.
But tropical regions have the greatest number of species. Frogs are classified as amphibians. Most amphibians, including most frogs, spend part of their life as a water animal and part as a land animal. Frogs are related to toads but differ from them in several ways. The section Kinds of frogs describes the basic differences between frogs and toads.
