''Scaphiopus'' is a genus of North American amphibian commonly referred to as the Southern Spadefoot Toads. They differ greatly from true toads (those of the family Bufonidae) by having eyes with vertical pupils, no parotoid gland, 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 scientific names means ‘spade-foot’ as well, from the Ancient Greek ' (, ‘spade, shovel’) and ' (, ‘foot, leg’). == Species == ''Scaphiopus'' species were once classified with their European cousins in the family Pelobatidae, but have since been reclassified to their own family, Scaphiopodidae with other North American species. There are three species in the genus ''Scaphiopus'': *Couch's Spadefoot, ''Scaphiopus couchii'' Baird, 1854 *Eastern Spadefoot, ''Scaphiopus holbrookii'' (Harlan, 1835) *Hurter's Spadefoot, ''Scaphiopus hurterii'' Strecker, 1910 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scaphiopus」の詳細全文を読む スポンサード リンク
