Northern Green Frog (Rana clamitans melanota)

Green Frog (Rana clamitans) 

The Northern Green Frog (Rana clamitans melanota) is an amphibian of order Anura, True Frog Family (Ranidae), genus Rana and species clamitans and subspecies melanota. It grows to a length of two to four inches (five to ten centimeters). The body is green and yellow above with patches of gray that may give this frog a gray appearance particularly under water. Its belly is white with dark spots or lines. The Northern Green Frog resembles a small Bullfrog but has prominent ridges of skin folds that extend from behind its ears, along the sides to just before the groin as seen in the photograph above. The hind feet are not fully webbed as in the Bullfrog. The male has a yellow throat and swollen thumbs. A southern subspecies, Bronze Frog (Rana clamitans clamitas), is brown but not found in Maine.

The family and genus names come from the Latin for "frog." The species name is from the Latin for "noisy."

These frogs mate in spring and summer and produce as many as 7,000 eggs in one laying. The eggs are attached in three or four masses to submerged vegetation. Female tadpoles can require up to three years to mature during which they are subject to predation. Male tadpoles mature in about a year.

Their diet consists of  invertebrates, fish, birds, small animals, including other frogs and tadpoles. This frog is very common on Mount Desert Island.

The Northern Green Frog (Rana clamitans melantota) lives on the shores of lakes and ponds in shallow water and sometimes among decaying wood. Although it will avoid capture, this frog is not particularly alarmed when handled. It is the frog most commonly caught by children around French Hill Pond.

These frogs are frequently kept as pets and are sold in pet stores.
