Frogs and Toads of Ohio
The Green Frog and American Bullfrog looks the same but the Bullfrog can grow larger and they lack a dorsal ridge down their back.
Pickeral Frog, Northern Leopard Frog, and Southern Leopard Frog look very similar to each other because of the spots but the Pickeral frog’s spots are more rectangular than the Leopard Frogs. The Southern Leopard Frog has less spots on the side of its side compared to the Northern Leopard Frog.
Wood has a raccoon like mask on its face that makes it easy to identify.
The Northern Cricket Frog is the only Cricket Frog in the state. It has no real distinct marks like the other frogs on this list.
The Gray Tree Frogs are identical besides their calls. They are the largest tree frogs in the state.
Here is a video of some Eastern Gray Tree Frogs calling that I took.
The Mountain Chorus frog looks similar to the other Chorus frogs in the state but it has a specific shape on its back that looks like this )(.
The Midland Chorus Frog has three distinct stripes down their back. It’s similar to the Spring Peeper and the Mountain Chorus Frog.
Spring Peeper can be identified by the X marking on its back.
The American Toad and the Fowler’s Toad look very much alike. The differences between the two are in the back of their heads.
The American Toad’s parotid gland is separated from the craniel crest while the Fowler’s Toad’s touches.
Eastern Spadefoot Toad is the only spadefoot toad in the state so just look for the toad with a spade on its rear feet.
