The Smooth Sided Toad is also known as the Spotted Toad. These toads are brown, and unlike other toads, they are smooth-skinned. They may grow to seven inches in length. The pupils are horizontal. The parotoid glands (glands resembling warts, occurring behind the eyes or on the neck and shoulders) are usually conspicuous and may be large. The tympanum is clearly visible. The limbs are short and strong, the fingers free, and the toes more or less webbed. Males are smaller then females.
