The Alabama waterdog is a medium-sized perennibranch salamander inhabiting rivers and streams of Alabama. It is listed as endangered by the IUCN and the United States Fish and Wildlife Service.
The Cumberland dusky salamander is a species of salamander in the family of lungless salamanders, Plethodontidae. It is endemic to the United States. Its natural habitats are temperate forests and rivers. This species is threatened by habitat loss.
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.
The Apalachicola dusky salamander is a species of salamander in the family Plethodontidae. It is threatened by habitat loss.
The Carolina mountain dusky salamander is a species of salamander in the family Plethodontidae.
The dwarf black-bellied salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States.
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 a separate species, the southern dusky salamander. 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 into the panhandle of Florida and west to Louisiana. 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.
The imitator salamander is a species of salamander in the family Plethodontidae. It is endemic to the Appalachian Mountains in the Eastern United States.
The shovelnose salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States.
The seal salamander is a species of lungless salamander that is endemic to the Eastern United States.
The Allegheny Mountain dusky salamander is a species in the Plethodontidae family. It is found in the eastern United States and southern Quebec, Canada. Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater springs, and rocky areas.
The Ocoee salamander is a species of salamander in the family Plethodontidae.
The Blue Ridge dusky salamander is a species of salamander in the family Plethodontidae.
The blackbelly salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are rivers, intermittent rivers, and freshwater springs. It is threatened by habitat loss.
The black mountain salamander is a species of salamander in the family Plethodontidae.
The pygmy salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States in the southern Appalachians in North Carolina and Tennessee.
The northern pygmy salamander is a terrestrial species of salamander in the family Plethodontidae and genus Desmognathus. Along with the southern pygmy and the seepage salamander, these are some of the smallest salamander species in North America and can be found in higher elevations in the southern Appalachians.
