Desmognathus fuscus
Identification
The Northern Dusky Salamander is a grayish-brown salamander that is noticeably chunkier than the Northern Two-lined Salamander that they often share their habitat with. Adults range from 3 – 5½ inches long. On young individuals, white lines outlined in black start at the eye and angle down to their jaw. These lines fade as the salamanders age. Their back legs are larger and stronger then their front legs, and their tail is partially keeled.
They lay their eggs primarily under moss over seeps, and the females remain with the eggs until they hatch.

Range/Habitat

Northern Dusky Salamanders are found statewide, but less often in the Northeast Kingdom.
