American Toad Anaxyrus americanus

Southern Toad (Anaxyrus terrestris)

The Oak Toad is the most easily identifiable toad out of the group of four. It is the smallest of the group and has a light line down its back. The Oak Toad also has orange on the bottom of its feet. The remaining three species of toads in North Carolina are a lot harder to distinguish between. To identify the differences, you have to look at the top of the head. The Southern Toad has knobs on the back of its head. The Fowler’s Toad’s parotid gland touches its postorbital ridge around its eye while the American Toads’s parotid gland does not touch or connected to it by a spur. Here’s an easy map I found that helps me.
