Checklist of Amphibian Species and Identification Guide

Green Frog, Rana clamitans

Bronze Frog
The Green Frog is divided into teo subspecies, the Bronze Frog, R. c. clamitans, and the Northern Green Frog, R. c. melanota. The Bronze Frog is a medium sized frog attaining lengths around 3 inches; the Northern Green Frog is slightly larger reaching sizes of 3.5 inches. In both the dorsolateral folds or ridges do not end on the body and do not continue to the groin. As in some other species of frogs, the gender of the individual frog can be determined by the size of the tympanic membrane relative to the eye. It is considerably larger than the eye in males and about the same size as the eye in females. Also, males are often a bright yellow as shown below right. Bronze Frogs are so named because of the brown or bronze coloration on their dorsal surface, as in the photo on the right. Northern Green Frogs (the four photos below) usually have more green coloring on the back, but are often more brown than green. They also tend to have dark markings on the back as in the photo below left.
