(Click for family gallery)The largest family of extant salamanders with over 400 species. All members of this assemblage lack lungs, relying on cutaneous respiration instead and possess naso-labial grooves which aid in chemoreception. This group was once thought to have arisen out of the Appalachian Mountains in the eastern United States, which remains a biodiversity hotspot for this family. Members within this group have adapted to stream, arboreal, terrestrial, fossorial (underground) and cave habitats. Currently there are two subfamilies, the Hemidactylinae and Plethodontinae, of which the latter has species capable of ballistically projecting their tongue (along with tongue skeleton) to capture prey (as in Hydromantes) as well as having webbed feet (tribe Bolitoglossini). Generalized in body form with four fingers and five toes (except when reduced to four toes in miniaturized species), plethodontids cover the spectrum of salamander sizes. Most species are direct developers.
With only a handful of exceptions, this family is found in the New World and extends from southern Canada down through Bolivia and Brazil. The exceptions to the New World include six species in the Middle Western Mediterranean in Europe (members of the genus Hydromantes, which also occurs in California) and a single species known from Asia (Karsenia). It includes the only group of tropical salamanders which account for about 2/3 of the species and 40% of all salamanders.
