Spea

Spea is a genus of North American amphibian commonly referred to as the western spadefoot toads. They differ greatly from true toads (those of the family Bufonidae) by having eyes with vertical pupils, no parotoid glands, and relatively smooth skin. Their most distinctive feature is a spade-like projection on their hind feet, from which their common name is derived. This projection enables spadefoot toads to dig in loose soils with ease. Its name is from the Ancient Greek speos (σπέος, ‘cave, cavern’)[1]
