Frogs and Toads have a fairly simple structure. Broad bodies, no identifiable neck, no tail and four legs. They have a wide mouth and tiny nostrils on their snout. Prominent eyes for almost 360' vision. And moist smooth or rough skin.

The links above explore the many different and unusual features of frog biology. From their movement, vision, breathing, skin, hearing, temperature control, and smell to their strange reproduction processes.
