How many legs does a typical adult frog have?

A typical adult frog has four legs. Its two front legs support and steer the body, while its two powerful hind legs provide the main force for jumping and swimming.

Frogs begin life very differently. A newly hatched frog is a legless tadpole that swims with a tail. During metamorphosis, hind legs develop first, followed by the front legs; the tail is gradually absorbed and reused by the developing animal. By adulthood, the frog has the familiar four-limbed body plan shared by most land vertebrates.

The hind legs are usually much longer and more muscular than the forelegs. In many species, the toes of the rear feet are connected by webbing, making them effective paddles. Tree frogs may also have expanded toe pads for gripping leaves and branches, while burrowing frogs can have specialized feet for digging.

“Typical” matters because amphibians show unusual variation. Some frogs have reduced or missing digits, deformities, or highly specialized body forms, but these do not change the standard quiz answer. Frogs are also often confused with salamanders: salamanders generally retain a tail as adults, whereas adult frogs normally do not.
