Field Notes
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 not webbed, but the feet have webbing between the digits with the exception of the fourth toe.
Habitat:
small freshwater pond
Notes:
After a "challenge" this week to find a new spotting in my lowest category of organisms, I set out to find me some amphibians. I struck out for 3 days until I hit the mother load! A pond full of bullfrogs! This was one of many I photographed!
