Plethodontidae, or lungless salamanders, are a family of salamanders. With over 500 species, lungless salamanders are by far the largest family of salamanders in terms of their diversity. Most species are native to the Western Hemisphere, from British Columbia to Brazil. Only two extant genera occur in the Eastern Hemisphere: Speleomantes and Karsenia.
Plethodon is a genus of salamanders in the family Plethodontidae. They are commonly known as woodland salamanders. All members of the genus are endemic to North America. They have no aquatic larval stage. In some species, such as the red-backed salamander. Young hatch in the adult form. Members of Plethodon primarily eat small invertebrates. The earliest known fossils of this genus are from the Hemphillian of Tennessee in the United States.
The red-backed salamander is a small, hardy woodland salamander species in the family Plethodontidae. It is also known as the redback salamander, eastern red-backed salamander, or the northern red-backed salamander to distinguish it from the southern red-backed salamander. The species inhabits wooded slopes in eastern North America, west to Missouri, south to North Carolina, and north from southern Quebec and the Maritime provinces in Canada to Minnesota. It is one of 56 species in the genus Plethodon. Red-backed salamanders are notable for their color polymorphism and primarily display two color morph varieties, which differ in physiology and anti-predator behavior.
The northern slimy salamander is a species of terrestrial plethodontid salamander found throughout much of the eastern two-thirds of the United States.
The Cheat Mountain salamander is a species of small woodland salamander in the family Plethodontidae. The species is found only on Cheat Mountain, and a few nearby mountains, in the eastern highlands of West Virginia. It and the West Virginia spring salamander are the only vertebrate species with geographic ranges restricted to that state.
The seepage salamander is a small, terrestrial species of salamander in the family Plethodontidae. It is endemic to the United States. They are found in small areas of Tennessee, North Carolina, Georgia, and Alabama. Its natural habitats are temperate forests, intermittent rivers, and freshwater springs. It gets its name from the seepages around which it lives. It is very similar in its appearance and life history to the pygmy salamander. These two species differ greatly from the other Desmognathus species. They are the smallest salamanders in the genus, measuring only 3–5 cm (1–2 in) in length. They are also the only two terrestrial, direct-developing Desmognathus species. However, the two species are not often seen to coexist, differing in distribution by elevation; although there are exceptions. The seepage salamander is currently listed as Near Threatened, with its numbers declining in most of states in which it is found. It is threatened by habitat loss, with logging having a major effect.
Desmognathus fuscus is a species of amphibian in the family Plethodontidae. The species is commonly called the dusky salamander or northern dusky salamander to distinguish it from populations in the southern United States which form several distinct species, the southern dusky salamanders. The northern dusky salamander is the most widespread representative of its genus in Canada. It can be found in eastern North America from extreme eastern Canada in New Brunswick south to South Carolina. The size of the species' total population is unknown, but is assumed to easily exceed 100,000. The species' habitat differs somewhat geographically; dusky salamanders in the northern part of the range prefer rocky woodland streams, seepages, and springs, while those in the south favor floodplains, sloughs, and muddy places along upland streams. They are most common where water is running or trickling. They hide under various objects, such as leaves or rocks, either in or near water. Alternatively, they may enter burrows for protection. The dusky salamander lays its eggs close to water under moss or rocks, in logs, or in stream-bank cavities. The larval stage which follows is normally aquatic.
Pseudoeurycea lineola, commonly known as the Veracruz worm salamander or Mexican slender salamander, is a species of salamander in the family Plethodontidae. It is endemic to the eastern slope of the Trans-Mexican Volcanic Belt near Cuautlapan, in the west-central Veracruz, Mexico, at elevations of 800–1,250 m (2,620–4,100 ft) above sea level. Molecular evidence suggests that it consists of two distinct species. It was the type species of genus Lineatriton.
The northern ravine salamander is a species of salamander in the family Plethodontidae. The species is endemic to the United States.
The Peaks of Otter salamander is a species of salamanders in the family Plethodontidae. It is endemic to the Peaks of Otter area in the Blue Ridge Mountains of Virginia. It is a montane salamander found at elevations above 442 m (1,450 ft), but more commonly above 760 m (2,490 ft). It can be locally common, but its distribution is small and patchy. This makes it vulnerable to local threats such as timber harvesting, recreational development, defoliation by gypsy moths, and spraying to control the latter.
The Cumberland Plateau salamander is a species of salamander in the family Plethodontidae. It is endemic to the Cumberland Plateau, the southeastern United States. Its natural habitat is temperate forests. It is threatened by habitat loss.
The Kiamichi slimy salamander is a species of salamander in the family Plethodontidae endemic to the United States, has a natural habitat of temperate forests, and is found over a small range. This nocturnal species is mainly threatened by habitat loss and was first described by Highton in 1989. It is rated as a vulnerable species by the International Union for Conservation of Nature.
Plethodon punctatus, commonly known as the Cow Knob salamander or white-spotted salamander, is a species of salamander in the family Plethodontidae. It is endemic to high mountain forests on the border of Virginia and West Virginia in the United States. Nearly all occurrences are on Shenandoah Mountain, Nathaniel Mountain and Great North Mountain in George Washington National Forest. Cow Knob salamanders are a member of the P. wehrlei species complex, which includes many other Appalachian salamanders historically referred to Plethodon wehrlei.
The Shenandoah salamander is a small, terrestrial salamander found exclusively in Shenandoah National Park in Virginia. The Shenandoah salamander inhabits a very small range of land on just three mountain peaks. Due to the small habitat range, interspecies competition, and climate change, the population of the Shenandoah salamander is vulnerable to extinction. Mitigating human effects on the habitat of the species will be essential in attempting to preserve and grow the population.
The Webster's salamander is a species of salamander in the family Plethodontidae. It is endemic to the southeast United States, in patchy and disjunct lowland subpopulations ranging from South Carolina to Louisiana. Its natural habitat is mixed mesophytic temperate forests, in association with rocky streams and outcrops.
Weller's salamander is a species of salamander in the family Plethodontidae. This species in endemic to the southeastern mountain range of the United States. It is mainly found in North Carolina near Grandfather Mountain. The salamanders have a unique metallic spotting which distinguishes them from other Plethodon species and other salamanders in the area. They mainly inhabit cool forests with rocky areas.
The Yonahlossee salamander is a particularly large woodland salamander from the southern Appalachian Mountains in the United States. The species is a member of the family Plethodontidae, which is characterized by being lungless and reproductive direct development. P. yonahlossee was first described in 1917 by E.R Dunn on a collection site on Grandfather Mountain in North Carolina. The common and specific name is of Native American origin, meaning “trail of the bear”. It is derived from Yonahlossee Road northeast of Linville, where the specimen was first described.
The red salamander is a species of salamander in the family (Plethodontidae) endemic to the eastern United States. Its skin is orange/red with random black spots. Its habitats are temperate forests, small creeks, ponds, forests, temperate shrubland, rivers, intermittent rivers, freshwater, trees springs. Overall this species is common and widespread, but locally it has declined because of habitat loss and it is considered threatened in Indiana and New York. Red salamanders eat insects, earthworms, spiders, small crustaceans, snails, and smaller salamanders. To eat, they extend their tongue to capture prey on the tip of it and retract it back into their mouths. The red salamander, as a member of the family Plethodontidae lacks lungs and respires through its skin.
The Ocmulgee slimy salamander is a species of salamander in the family Plethodontidae. It is endemic to the state of Georgia in the United States, where it is found in regions of the coastal plain and Piedmont that are associated with the Ocmulgee River drainage system. It is only known from a few counties, and due to this restricted range, it is at high risk of extinction. Many populations of this species are already experiencing precipitous declines, with some even possibly being extirpated.
The Blacksburg salamander is a species of salamander in the family Plethodontidae. It is endemic to the Southeastern United States, where it is restricted to a portion of the Appalachian Mountains in southwestern Virginia. Its common name refers the town of Blacksburg, Virginia, as many specimens were initially found in the vicinity of the town.
