[edit] Description
The Green Frog ranges from 2-4 inches (5-10 cm) in size, with the male having a large prominent tympanum and a yellow throat in contrast to the female's white throat and smaller eardrum. Dorsolateral ridges are prominent in contrast to the Bullfrog whose dorsolateral ridges are absent. Contrary to its name, it can be found in various colors (bronze, brown, and light green) depending on its habitat region.
[edit] Behavior
The Green Frog lives near shallow water, springs, brooks, swamps, and edges of ponds and lakes that have a considerable amount of vegetation. This frog is primarily nocturnal and is not as wary as many other species of frog. They rarely scream in alarm when captured. The call is often compared to the twang of a banjo string, usually given as a single note, but sometimes repeated rapidly several times to designate its territory. Its breeding season is from March to August. Eggs are typically laid in 3-4 small clutches that are attached to submerged vegetation.
[edit] Body Structure
The Green Frog has very important body parts. The lungs are where oxygen flows into the blood and where carbon dioxide is released into the air. The skin is very smoot and moist. It absorbs some oxygen through the skin. Its hind legs are long and has powerful leg muscles to make the frog an excellent leaper. The Green Frog has a 3-chambered heart like all amphibians. The mouth has teeth and nostril openings and the frog's tongue is attached at the front of its mouth--it flips out to catch insects. The Green Frog's large eyes give it excellentvision and allow it to see predators while it floats in the water
[edit] Subspecies
There are two recognized subspecies of Lithobates clamitans:
- Bronze Frog, Lithobates clamitans clamitans (Latreille, 1801)
- Northern Green Frog, Lithobates clamitans melanota (Rafinesque, 1820) The Green Frog is also widely know as one of the world's fasted Amphibian. A discovery Owen Price made recently in 2004, January the 3rd where he tested many Frogs pace. Overall Owen Price dertimned a great discovery
