American Bullfrog (Lithobates catesbeianus) - Ohio Herp Atlas

American Bullfrog Lithobates catesbeianus

The American Bullfrog is the largest frog in North America. The deep resonant call of the male Bullfrog can be heard reverberating from Ohio ponds, marshes, and large slow-moving streams from late April through late summer. Sometimes their call can be heard a mile away. Like most other frogs and toads, its tongue is fastened in the front of the mouth, enabling it to catch a wide variety of creatures. Its diet includes crayfish, insects, mice, small snakes and turtles, and other frogs. There have been reports of 37 finding birds, and even bats in the stomachs of Bullfrogs. As with its cousin the Green Frog, male and female Bullfrogs are distinguished from each other by the size of the ear drum. Females have ear drums about the size of their eyes; they are much larger in the males. Except during breeding season, when they go through an aggressive, loud, splashing courtship, Bullfrogs are rather solitary and are very territorial. The large tadpoles may take two or three years to complete metamorphosis, in some cases.
