Southern Toad

The southern toad is characterized by highly pronounced knobs and crests that occur on its head. The two crests run forward from the knobs and come close to one another near the snout. The overall coloring of this toad varies from brown, black, or red. It has no dark spots, and only one or two warts. Although it has long been suggested, humans do not get warts from touching toads. However, the material they secrete from the parotoid glands (located at the back of the head, behind the ears) may be irritating to human mucous membranes, but not toxic.
