The Cheoah Bald salamander is a species of salamander in the family Plethodontidae endemic to the state of North Carolina in the United States. Its natural habitat is temperate forests and it is threatened by habitat loss. It was formerly considered a variant of the red-cheeked salamander until it was found to be a distinct species.
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. The preferred habitat of this species is under logs and leaf litter in shaded hardwood forests and wooded floodplains, and often forages on the forest floor on wet nights. It was found that with increasing temperatures, the aggression in this species also increases. In the plethodon genus, species have a lungless morphology, restricting nearly all gas and water exchange transport to the body surface. This species mainly consumes insects, including ants, centipedes, springtails, crickets, millipedes, slugs, snout-beetles, and earthworms. Common predators of this species are gartersnakes, copperheads, and birds. One of their predator defense mechanisms is the release of noxious/sticky substances through the skin by the dorsal granular glands. Another predator deterrent is when touched, this species will freeze in place and become immobile. This species of Plethodon are mostly terrestrial and deposit their direct-developing eggs on land that omits the aquatic larval stage characteristic of most amphibians, therefore this species is not restricted to aquatic habitats for reproduction and dispersal. This species, along with other Plethodontid salamanders, are frequently parasitized by Trombicula mites.
The northern zigzag salamander is a species of salamander in the family Plethodontidae. It is endemic to the eastern United States and has been found in Illinois, Kentucky, Tennessee, Alabama, and Mississippi. The northern zigzag salamander's natural habitat includes temperate forests, rocky areas, and caves. It is threatened by habitat loss.
The Del Norte salamander is a species of salamander in the family Plethodontidae endemic to the United States in southwestern Oregon and northwestern California.
The Fourche Mountain salamander is a species of salamander in the family Plethodontidae endemic to the Ouachita Mountains in the central United States. Its natural habitat is temperate forests and it is threatened by habitat loss.
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. 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.
The Larch Mountain salamander is a species of salamander in the family Plethodontidae endemic to the United States. It occurs in the Cascade Mountains of southern Washington and northern Oregon. In Washington, it occurs from the Columbia River Gorge to just north of Snoqualmie Pass. Its natural habitats are temperate forests and rocky areas. It is threatened by habitat loss.
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. Like other salamanders, they do not migrate or aggregate during breeding season. It is threatened by habitat loss.
The Jemez Mountains salamander is a species of salamander in the family Plethodontidae endemic to New Mexico in the United States. Its natural habitat is temperate forests. It is threatened by habitat loss, is in rapid decline, and was placed on the IUCN Red List in 2013.
The Big Levels salamander is a species of salamander in the family Plethodontidae. It is endemic to Virginia in the eastern United States. First described in 2004, it derives its specific name, sherando, from Sherando Lake in the George Washington National Forest. Its common name refers to the Big Levels area of southeastern Augusta County, Virginia, a series of flat to gently rolling mountain tops in the Blue Ridge Mountains, where it was found.
The Shenandoah Mountain salamander is a species of salamander in the family Plethodontidae native to the eastern United States. It should not be confused with the Shenandoah salamander, which inhabits Shenandoah National Park, east of Shenandoah Mountain.
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.
