The green frog, Rana clamitans, is a common frog that is native to eastern North America, but has been introduced throughout much of western North America, including Utah. This frog usually inhabits the margins of permanent or semi-permanent water bodies, but young individuals may be found in temporary pools.

The green frog lays one or two clutches of eggs in spring or summer, and young develop in shallow, slow-moving water. Adult green frogs primarily eat terrestrial insects, but small amphibians are also occasionally consumed. Larvae (tadpoles) eat algae, organic debris, and any small organisms found in the water. The green frog has a green, brown, or bronze back that can be plain or darkly spotted, and a white belly with irregular blotches.
