They are typically characterized by a superficially lizard -like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body ...
Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm.

Pseudoeurycea ruficauda, also known as the orange-tailed agile salamander, is a species of salamander in the family Plethodontidae. It is endemic to the Sierra Mazateca , a part of Sierra Madre de Oaxaca of Mexico.
Phylogenetic analyses have however shown that species in the Salamandridae traditionally called newts do form a monophyletic group. [1] [16] [17] Other, more distantly related salamander families also contain fully or in part aquatic species, such as the mole salamanders, the Proteidae, or the Sirenidae.

Researchers heard males’ unique calls and found the new species near a forest stream in China. Pregnant creature — with ‘light orange’ bumps on its skin — is a new species. See it
This species is found in the southern Appalachian Mountains, mostly south of Virginia. To the north is a similar salamander, Eurycea bislineata, or the northern two-lined salamander. Its genus, Eurycea contains 33 species and includes taxa that have either a metamorphic life cycle or larval-form paedomorphosis. In species that metamorphose ...
