Classification

Phylum: Chordata
Subphylum: Vertebrata
Class: Amphibia
Order: Anura
Family: Ranidae

Description

There are two subspecies based on color. The Green Frog is the green subspecies R. clamitans melanota. It has a green or brown back covered with brownish or grey blotches. The Bronze Frog is the bronze subspecies R. clamitans clamitans. It has a bronze or brownish back and may be quite plain, with no blotches. The belly of both subspecies is white with dark spots or elongated blotches. Length ranges from 5.4 - 10.2 cm (2 - 4 in).

Life Cycle

This frog breeds from April through late summer. Fertilization is external. The female lays surface masses of up to 3,000 eggs in shallow water. Hatching occurs in one to two weeks. The larval stage is extended, and transformation from tadpoles to frogs does not occur for several months. This frog is an opportunistic feeder and eats small frogs, worms, insects, and other small, unwary organisms. It frequents shallow waters and vegetation surrounding streams, ponds, marshes, springs, and swamps. This is a secretive frog, hiding in logs, rotting wood, and under debris during the day. It may be found in the same habitats as Bullfrogs, but it prefers smaller bodies of water. Like the Bullfrog, it needs permanent water, because the tadpole stage lasts for several months.

Range

Green Frog / Bronze Frog Region Map This species is found along the eastern coast of the United States and well into the eastern Canadian Provinces. The Bronze Frog is the southern subspecies, occurring on the Coastal Plain. The Green Frog extends from northern Georgia to Canada.
