Southern Toad

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 South 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.

  1. I saw a black toad with orange spots the other day and was wondering if it was poisonous. I have 3 young children and a dog who love to outside, need to know. Thanks

    1. It has some toxins in its skin, if your kids touch the toad, just make sure they wash their hands. Also don’t let your kids eat the toad. If the dog eats it, it might feel unwell for a few days and might puke or have diarrhea
