genus_authority = Holbrook, 1836"Scaphiopus" is a
genus ofNorth America namphibian commonly referred to as the southern spadefoot toads. They differ greatly from truetoad s (those of the familyBufonidae ) by havingeye s with verticalpupil s, noparotoid gland , and relatively smoothskin . Their most distinctive feature is a spade-like projection on their hind feet, which their common name is derived from. This projection enables spadefoot toads to dig in loose soils with ease.Species
"Scaphiopus" species were once classified with their
Europe an cousins in the familyPelobatidae , but have since been reclassified to their own family,Scaphiopodidae with other North American species. There are threespecies in the genus "Scaphiopus":*Couch's Spadefoot, "
Scaphiopus couchii " (Baird, 1854)
*Eastern Spadefoot, "Scaphiopus holbrookii " (Harlan, 1835)
*Hurter's Spadefoot, "Scaphiopus hurterii " (Strecker , 1910)Geographic range
Spadefoot toads are found throughout the
United States and into northernMexico . They tend to prefer dry, grassland areas with loose, sandy soils that flood in therainy season .Description
"Scaphiopus" are generally colored appropriately with
green s andbrown s tocamouflage themselves in their native habitat. At adult size they are usually not much larger than 8 cm.Behaviour, Diet & Reproduction
Spadefoot toads are
nocturnal and are rarely seen when it hasn't rained recently. They spend most of the time during thedry season buried in the ground inaestivation . When it rains, they emerge to feed oninvertebrate s and to breed invernal pool s. They have one of the fastest reproductive cycles of any amphibian species. Once laid, eggs hatch in a matter of a day or two. Thetadpole s are capable of developing to froglets within a couple of weeks. This feature is primarily due to fact that most of their breeding areas dry quickly once the rainy season is over.Related species
