Seal Salamander

Scientific Name: Desmognathus monticola
Size: 3-5 inches (8-12.5 cm) in length
Status: Abundant

Habitat:
Close to or in small to medium-sized mountain streams.

Description:
Medium-sized heavy bodied species. The background color is light brown to grayish with reticulated, mottled, or wormy dark brown to black markings. In some individuals these markings maybe absent or reduced. The sides of the body are mottled and often have a single line of white spots between the forelimbs and hind legs. The underside, chin and underside of the appendages are white to light grey. Melanophores on the venter are uniformly spaced so that the ventral lacks mottling. The head is mottles with brown or black. The toe tips are black and are darker than the other part of the toes. The tail is strongly compressed laterally with a sharp well defined knife-like dorsal keel. Salamander in the Desmognathus genus are easily identified by the light line that extends from the eye to the angel of the jaw.
