American bullfrog

Description:

The dorsal surface of the bullfrog has an olive green basal color, either plain or with a mottling and banding of grayish-brown. The ventral surface is off-white blotched with yellow or gray. There is often a marked contrast in color between the green upper lip and the pale lower lip. The eyes are prominent with brown irises and horizontal almond-shaped pupils. The tympani (eardrums) are easily seen and the dorsolateral folds of skin end close to them. The limbs are blotched or banded with gray. The forelegs are short and sturdy and the hind legs long. The hands are unwebbed but the feet have webbing between the digits with the exception of the fourth toe. Bullfrogs are dimorphic with males being smaller than females, having a yellow throat and having tympani larger than their eyes whereas the tympani in females are about the same size as the eyes. Bullfrogs measure about 3.6 to 6 in (9 to 15 cm) from snout to vent. They grow fast in the first eight months of life, typically increasing in weight from 5 to 175 g (0.18 to 6.2 oz), and large mature individuals can weigh up to 500 g (1.1 lb). Exceptional bullfrogs can possibly attain 800 g (1.8 lb) and measure up to 8 in (20 cm) in length. (information from Wikipedia)
