Scaphiopodidae, the Spadefoot toad family, is found in North America. They are known for the keratinized spade on their foot that is used for digging. They live mostly in the desert and spend most of the time underground. They are different from true toads of the family Bufonidae because they do not have a parotoid gland and posses smoother skin.
The two genera are Spea and Scaphiopus. Spea is the western spadefoot toads. Scaphiopus is the eastern spadefoot toads.
