Green Frog (Lithobates clamitans)
Description: 2 - 4 inches. Green Frogs are green and may have darker green or brown mottling. The belly is light colored, but it may have some dark markings on it. There is a ridge that starts behind each eye and extends all the way down the length of the body (dorsolateral folds).
Similar Species: Bullfrogs are similar in appearance, but the ridge behind the eye wraps around the ear drum (tympanum) only, and does not extend down the body.
