Black Mountain Salamander
Desmognathus welteri · also called black mountain salamanders
Along a shaded mountain stream bank in the central Appalachians, a black mountain salamander forages within reach of the water’s edge, its dark, mottled pattern overlapping so closely with several similar dusky salamander relatives nearby that only its precise location gives away which species it actually is.
Overview
The black mountain salamander, Desmognathus welteri, is a large, robust amphibian native to mountain stream habitat across a range of the central Appalachian region, including parts of Kentucky, Virginia, West Virginia, and Tennessee. Its considerable size within its genus, close dependence on streamside moisture, and near-identical appearance to several overlapping dusky salamander relatives make it a representative example of just how visually cryptic Appalachian stream salamanders can be.
A salamander best identified by where you find it
With so many similarly dark, mottled dusky salamander species sharing overlapping stretches of Appalachian stream habitat, working out exactly which one is in hand often comes down to knowing precisely where the water is flowing.
Status
Least Concern — widespread and stable across suitable mountain stream habitat throughout the central Appalachian region.
Black Mountain Salamander: common questions
How can you tell a black mountain salamander from other dusky salamanders?
This species overlaps closely in appearance with several other dark, mottled dusky salamander species sharing parts of its central Appalachian range, so appearance alone is often unreliable, and confirming identification typically depends more on precise locality and, where necessary, genetic testing than on any single visible feature.
Why does the black mountain salamander stay so close to streams?
This species depends on the consistent moisture provided by mountain stream banks, seepages, and splash zones both as an aquatic larva and as a semi-terrestrial adult, and straying far from this reliable moisture source would leave it vulnerable to drying out in a way its physiology is not adapted to tolerate.
How big does a black mountain salamander get?
This species is one of the larger members of its genus, with a robust, muscular build suited to holding its position along fast mountain stream banks, generally larger than several of the smaller dusky salamander species found in overlapping parts of its range.
Where is the black mountain salamander found?
This species is native to mountain stream habitat across a range of the central Appalachian region, including parts of Kentucky, Virginia, West Virginia, and Tennessee, generally remaining within cool, well-shaded stream corridors throughout that range.
