Slender Salamanders is the name often given to Plethodontid (lungless) salamanders of the genus Batrachoseps. They are distinguished from other lungless salamanders by their four toes on each foot. Subfamilies Desmognathinae Plethodontinae Lungless salamanders (Family Plethodontidae) are salamanders which do not have lungs and instead conduct respiration through their skin and the tissues lining their mouth. ... Suborders Cryptobranchoidea Salamandroidea Sirenoidea Salamander is the common name applied to approximately 500 amphibian vertebrates with slender bodies, short legs, and long tails (order Caudata or Urodela). ...
Species in this genus include:
California slender salamander - (Batrachoseps attenuatus)
Santa Lucia slender salamander - (Batrachoseps luciae)
San Simeon slender salamander - (Batrachoseps incognitus)
Lesser slender salamander - (Batrachoseps minor)
The taxonomy of this genus is still uncertain. Some species may in fact be subspecies of others, and some subspecies may be distinct species of their own. Genetic analysis is in process.
Batrachoseps relictus (Relictual slender salamander) - Although originally described from several seepage areas in the lower Kern River Canyon, it has not been found there since the early 1970s and may well be extirpated from that area.
Batrachoseps "Breckenridge" (Breckenridge Mountain slender salamander) - This is an undescribed species known only from a single seepage on the southeastern flank of Breckenridge Mountain at 6300 ft. First collected in 1979, the site was severely damaged by the re-routing of a logging road through the seep area.
Batrachoseps - Although Pleistocene climate shifts had considerable effects on the distribution of many plants and animals in the American southwest, their role in explaining slender salamander distribution is probably minor.
