Plethodon is a genus of salamanders in the family Plethodontidae. They are also known as woodland salamanders or, more rarely, slimy salamanders. All members of the genus are endemic to North America. They have no aquatic larval stage. In some species, such as Plethodon cinereus, the red-backed salamander, eggs are laid underneath a stone or log. 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. 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 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. 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 Cheat Mountain salamander is a species of small woodland salamander 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 ranges restricted to that state.
The Blue Ridge gray-cheeked salamander is a species of salamander in the family Plethodontidae endemic to the Blue Ridge Mountains of North Carolina, United States. It is one of 55 species in the genus Plethodon and one of the most recently to be described. Its natural habitat is temperate forests. It is threatened by habitat loss.
The Scott Bar salamander is a species of salamander in the family Plethodontidae, endemic to the United States, where it is restricted to a very small range in the Scott River drainage in Siskiyou County, California, at altitudes between 700 and 1,300 metres above sea level. Described in 2005, it is one of the most recently described species in the large genus Plethodon.
The white-spotted slimy salamander is a species of salamander in the family Plethodontidae endemic to the Eastern United States. It is one of 55 species in the genus Plethodon, and was one of the first to be described of its cogeners.
Dunn's salamander is a species of salamander in the family Plethodontidae endemic to the western United States.
The northern ravine salamander is a species of salamander in the family Plethodontidae endemic to the United States. It has been found in Indiana, Ohio, Kentucky, Pennsylvania and West Virginia. Its natural habitats are temperate forests and rocky areas. The species is listed as Least Concern on the IUCN Red List of Threatened Species.
The valley and ridge salamander is a species of salamander in the family Plethodontidae endemic to the Appalachian Mountains in the eastern United States.
The Peaks of Otter salamander is a species of salamanders in the family Plethodontidae, endemic to the Peaks of Otter area in the Blue Ridge Mountains of Virginia.
The Cumberland Plateau salamander is a species of salamander in the family Plethodontidae endemic to the 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 data deficient species by the International Union for Conservation of Nature.
The South Mountain gray-cheeked salamander is a species of salamander in the family Plethodontidae, endemic to the state of North Carolina in the United States, where it is only found in the South Mountains. It was formerly considered a variant of the red-cheeked salamander. Its natural habitat is temperate forests. It is threatened by habitat loss.
The northern gray-cheeked salamander is a species of salamander in the family Plethodontidae and endemic to the Blue Ridge Mountains and Appalachian Mountains in the eastern United States. It is closely related to the Red-cheeked salamander and the Red-legged salamander. Its natural habitat is temperate forests. It is found under moss, rocks, logs, and bark in cool, moist forests above 2500 feet. Especially found in spruce-fir forests. The Gray-cheeked Salamander commonly eats millipedes, earthworms, crane flies, spiders, and centipedes and less commonly eats ants, mites, and springtails. They eat spiders, moths, flies, beetles, bees, and snails. The male and female perform a courtship, where the male nudges the female with his snout, does a foot dance, then circles under the female and the two then walk together. It is threatened by habitat loss.
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 Shenandoah Mountain salamander, scientific name Plethodon virginia, is a species of salamander in the family Plethodontidae native to the Eastern United States.
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. These 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. This species is currently threatened by population fragmentation and habitat degradation/loss.
