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 long-toed salamander is a mole salamander in the family Ambystomatidae. This species, typically 4.1–8.9 cm (1.6–3.5 in) long when mature, is characterized by its mottled black, brown, and yellow pigmentation, and its long outer fourth toe on the hind limbs. Analysis of fossil records, genetics, and biogeography suggest A. macrodactylum and A. laterale are descended from a common ancestor that gained access to the western Cordillera with the loss of the mid-continental seaway toward the Paleocene.
The northern slimy salamander is a species of terrestrial plethodontid salamander found throughout much of the eastern two-thirds of the United States.
Van Dyke's salamander is a small woodland salamander in the family Plethodontidae, the lungless salamanders. These animals breathe through their skin and are largely terrestrial. Compared to other salamanders in Plethodon it is relatively stocky with long legs. Usually associated with streams, seepages, and rock outcrops, it is endemic to Washington where it is found in a limited number of small, isolated populations.
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 red-cheeked salamander, also known as the Jordan's salamander, Jordan's redcheek salamander, or Appalachian woodland salamander, is a species of salamander in the family Plethodontidae. It is endemic to the Appalachian Mountains in the southeastern United States.
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 ravine salamander is a species of salamander in the family Plethodontidae. The species is endemic to the United States, and it is threatened by habitat loss.
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 Idaho giant salamander is a species of salamander. There are three closely related species to this taxon: D. ensatus,, D. copei and D. tenebrosus also known as the.
The Idaho pocket gopher is a species of rodent in the family Geomyidae. It is rather small, with a lightly built skull. Its fur color varies through the body and between individuals. Found in the western United States, it inhabits savannas, shrubland, and grasslands. Individuals live alone in burrows, staying active year-round. Many aspects of its behavior and biology are not well understood. The species is classified as being of least-concern by the International Union for the Conservation of Nature.
There are 14 species of amphibians and 5 species of reptiles known to occur in Mount Rainier National Park.
