Status
Seal Salamander (Desmognathus monticola) is a stout, heavy-bodied Desmognathus, with bulging eyes and a keeled tail. The oddly robust, portly shape is said to be reminiscent of a seal. As with other members of the genus, coloration is extremely variable. Generally strongly-marked, this species also shows a strongly-demarcated pale belly. Seal Salamanders in Maryland are restricted to in Garrett and Allegany Counties, where they inhabit banks of cool, well-oxygenated streams. They spend the day resting in burrows, and are primarily nocturnal (Conant & Collins, 1998; Maryland DNR site). This salamander breeds from autumn into early spring.

The seal salamander (Desmognathus monticola) is a species of lungless salamander that is endemic to the Eastern United States.[2]
Distribution and habitat
[edit]The seal salamander can be found from southwestern Pennsylvania and south through Appalachian Mountains areas of high elevation in West Virginia, western Maryland, western and northern Virginia, eastern Kentucky, western North Carolina, eastern Tennessee, western South Carolina, and northern Georgia to central Alabama. There are also disjunctive populations in southern Alabama as well as at the very western end of the Florida panhandle. In the north of its range, it has not been observed north or west of the Ohio River.[1]
An introduced population is present in Benton County, Arkansas.[3][4]
Its habitat includes rocky mountain streams, spring-fed brooks in the ravines of deciduous forests, muddy sections of streams and seepages. The total adult population size of the species is assumed to exceed 100,000.[1]
Etymology
[edit]The genus name Desmognathus refers to the characteristic bundle of ligaments that connect to the jaw in this species group.[5] The comes from the Greek words desmos, which means "ligament," and gnathos which means "jaw". The specific epithet monticola comes from Latin and means "mountaineer" or "highlander," in reference to the high-elevations where this species is commonly found.[5]
