The spotted-tail cave salamander (Eurycea lucifuga), a lungless salamander endemic to caves of the eastern United States Eurycea (of North America) and Speleomantes (of Italy and France) are two genera of lungless salamanders with so many individual species termed "cave salamanders" that the entire group is sometimes so designated.
The name 'cave salamander' can be confusing because the term is also used more generally to describe cave-dwelling salamanders. Despite its name, the cave salamander is much less cave adapted than other cave-dwelling salamanders like the olm or Texas blind salamander. Unlike the more cave-adapted species, the cave salamander is brightly ...
The olm (German: ⓘ) or proteus (Proteus anguinus) is an aquatic salamander which is the only species in the genus Proteus of the family Proteidae [2] and the only exclusively cave-dwelling chordate species found in Europe; the family's other extant genus is Necturus.
Cave species dwelling in darkness lack pigmentation and have a translucent pink or pearlescent appearance. [8] Salamanders range in size from the minute salamanders, with a total length of 27 mm (1 + 1 ⁄ 8 in), including the tail, to the Chinese giant salamander which reaches 1.8 m (6 ft
G. palleucus lives in caves and is dependent on the quality of the water in the streams that flow through them. Threats it faces include pollution, siltation, flooding, increased water flow and the filling of sinkholes and dumping of trash. This salamander is known from about two dozen sites but probably occurs in other cave systems.
As larvae the western grotto salamander lives in springs and streams near cave entrances. [1] As adults, They migrate deep into the caves themselves and live out their lives underground. [1] They prefer waters between 5.5 and 16.5 °C, and feed on small, cave-dwelling invertebrates such as Gammarus, though they are also known to eat guano as well.
This also leads to reduced sampling for study, which has led to some uncertainty in the taxonomic classification; some sources consider all species of Texas cave salamanders to be subspecies of the Texas salamander. Eurycea neotenes and Eurycea rathbuni also live in caves and eat small insects and spiders.
Eurycea longicauda, commonly known as the long-tailed salamander [5] or longtail salamander, [6] is a species of lungless salamander native to the Appalachian Region of the eastern United States. It is a " cave salamander " that frequents twilight zones of caves and also inhabits springs and surrounding forest.
