Scaphiopodidae, the American Spadefoot toad family, is found in North America. Try not to confuse it with Pelobatidae, the European Spadefoot Toad family. They are known for the keratinized spade on their foot that is used for digging. They live mostly underground so they are hard to research. They are different from true toads of the family Bufonidae because they do not have a parotoid gland and posses smoother skin.
