Northern dusky salamanders are smooth-skinned and brown with a darker stripe on their back and a dark line from the eye to the mouth. It absorbs oxygen through the skin and membranous tissue located in the mouth and throat. As some populations have short larval stages, anti-predator mechanisms are probably similar to those of the eggs—cryptic sites with maternal brooding. Their biphasic life cycle includes an aquatic state of seven to 16 months, followed by a semi-terrestrial adult stage. [3][4][5] The larvae are predominantly aquatic and approximately 1.5 cm in length upon hatching. [3] Urbanization has resulted in the disappearance of the species in Mount Saint-Hellaire National Park in Quebec, as well as other areas. iii.

[3], Changes to stream flow or the groundwater supply, can have significant impacts on local salamander genetics and populations vis-à-vis loss of suitable aquatic or terrestrial habitat, bank instability from excessive runoff, or simply changes to the moisture in the terrestrial habitat. [3] known as maybe rodents or mice, The home range of the northern dusky salamander is limited to 1m2 to 3.6 m2. Furthermore, in summer, Allegheny Mountain Dusky Salamanders disperse to forested areas around the stream or other water source that serves as their home.

It eats a very wide variety of invertebrates. Larvae (not illustrated): Larvae are colored and patterned as the youngest juveniles described above but have short gills best seen with a hand lens. Hatchling salamanders emerge from their eggs with external gills and undergo a brief period as fully-aquatic larvae. These two characteristics will help differentiate The Allegheny Mountain Dusky Salamander from the Eastern Red-backed Salamander, and Northern and Southern Two-lined Salamanders. [15] The aquatic portion of the adult's diet is habitat specific and commensurate with the seasonal abundance and diversity of invertebrates. Ecology and Conservation. [3][6][7] The dusky salamander also has a naso-labial groove, which aids olfaction, and thus the ability to search out mates and prey through smell.

There is a small population in extreme southeastern Quebec, Canada, in the foothills of the Adirondacks, and a few isolated populations in northeast Kentucky and west-central Georgia (Conant and Collins 1998). Also, dusky salamanders have a larger snout than most other small stream inhabiting salamanders. The greatest threat is the silting up of the streams where it breeds due to logging activities, but when the streams recover, the salamanders move back into the area. [3] In winter, they remain in shallow running water, whereas adults overwinter in subterranean retreats or in streams, often remaining active throughout winter if the substrate doesn't freeze.
