Description:  The largest frog in Kentucky, this species ranges from 3.5-6 inches and larger.  Coloration ranges from green to brown, and can be plain or with some mottling of darker colors.  There are no ridges running down the back, as in the Green Frog.  Sex of Bullfrogs can be determined by observing the tympanum (eardrum).  In males the tympanum will be larger than the eye, and in females it will be the same size or smaller.

Habitat:  Usually found in permanent waters such as ponds, lakes, streams, creeks and wetlands, but may be found in temporary pools as well.

Behavior:  Calls of Bullfrogs are usually portrayed phonetically as 'jug-o-rum'.  The Bullfrog is a voracious eater.  Prey items include insects, fish, snails, slugs, salamanders, frogs, snakes, mice and small birds (basically anything it can fit into its mouth!).
