Description: A medium-sized frog: 7.5 to 12.5 cm (3 - 5 in), with dorso-lateral ridges that are well-defined, extending from the back of each eye down the back. The toes are extensively webbed and the second toe is longer than the first. Coloration is generally dark green but some individuals are more brown or yellow and all have small irregular black spots and a white to yellow ventrum. Specimens from cypress swamps are often very dark brown or almost black. Males often have a bright yellow throat and their tympanum is much larger than their eye (whereas the tympanum of females are about the same size as the eye)

Range and Habitat: Rana [Lithobates] clamitans can be found throughout our region in or near almost any inland water source such as: ponds, marshes, and along slow moving streams and rivers.

Habits: Although generally found close to water, during heavy rains, juveniles may move into wooded areas or meadows. During the winter, Rana [L.] clamitans will bury themselves in the mud at the bottom of the pond or marsh in order to keep from freezing.

Call: The mating call of Rana [L.] clamitans is a twang that is often likened to the sound of a plucked banjo string. As many as 6 other calls are also used: aggressive calls and growls, a release call, an alert call, an advertisement call, and a high-intensity advertisement call. Males can be reliably identified by their advertisement call.

Conservation Status: Rana [L.] clamitans is both locally and nationally abundant and is ranked as N5 in the U.S and S5 in Georgia.
