A number of features distinguish the plethodontids from other salamanders. Most significantly, they lack lungs, conducting respiration through their skin, and the tissues lining their mouths. [3] Some species of cave salamanders are neotenic, and keep their larval gills even as adults. Gills are absent in all other adult plethodontids. [13]
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela from the group Caudata. [2]
The seepage salamander is a very small and slender salamander, ranging from 4.4–5.7 cm (1.75–2.25 in). The adults possess vomerine teeth. [2] The tail is terete and rounded. The seepage salamander has a pale dorsal stripe, with a wide, wavy to almost straight shape, and ranging in color from yellow or tan to reddish brown. [4]
These salamanders are mostly terrestrial and eat invertebrates, although some species are known to eat smaller salamanders. They can be found throughout the US and some areas of Canada in damp forests or plains. This family contains some of the largest terrestrial salamanders in the world, the tiger salamander and the coastal giant salamander ...
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however.
The red-backed salamander (Plethodon cinereus) is a small, hardy woodland salamander species in the family Plethodontidae.It is also known as the redback salamander, [3] eastern red-backed salamander, [3] or the northern red-backed salamander to distinguish it from the southern red-backed salamander (Plethodon serratus).
Sirenidae, the sirens, are a family of neotenic aquatic salamanders. Family members have very small fore limbs and lack hind limbs altogether. [1] In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched together on the neck in both larval and adult
Plethodon is part of the family Plethodontidae (lungless salamanders) and the subfamily Plethodontinae.The genus Plethodon can be divided into two subgenera: the nominal subgenus Plethodon, which includes up to 49 eastern species (the bulk of diversity in the genus), and the subgenus Hightonia, [5] which includes 9 species native to the western part of North America.
