Medium-sized toad in which adults of the species can attain snout vent lengths between 41mm and 92mm. Males usually average between 42-82mm and females slightly larger between 44-92mm. Much larger specimens, however, have been found on islands along the coasts of Georgia, Florida, and South Carolina. The most distinguishing characteristic is the knobs found on the head which are actually extensions of the interorbital ridges. As usual with a member of the family Bufonidae, parotoid glands are present and the skin is warty. The warts are often spine-tipped. The spotted and mottled dorsal coloration can vary from shades of brick red to black. The ventral side is lighter. Post orbital ridges are not in contact with the parotoids but are connected to them by a backward projecting spur.
