What do Bullfrogs look like?
Bullfrogs are the largest frogs in North America. Their bodies are usually a dull green color, but may be brownish, and adults range in size from 3.5 to 6 inches long. Their external eardrum (tympaniomembrane) is large. The male and female are distinguished by the size of the eardrum. The female’s eardrum is approximately the size of the eye, while the male’s is larger than the eye. A bullfrog’s hind feet are fully webbed except for the last joint of the longest toe.
