Black-bellied Salamander

Desmognathus quadramaculatus

The Black-bellied Salamander can be found in cool, permanent streams in the Blue Ridge Mountains and Appalachian Ridge and Valley. Color pattern differences have been noted between southern and northern populations, but no subspecies are recognized.

Description: A large, robust salamander (3.5 to 8.0 inches in length) having mottled dark brown to black dorsum with lighter rusty brown blotches. Two rows of small, whitish dots occur along the length of each side of the body. A light line occurs from the eye to the corner of the jaw. Bellies are jet black in adults. Tails are triangular in cross-section and are strongly keeled.

Similar Species:

Habitat: Typically found in cool mountain streams. Also found in seepages, crevices, burrows on banks, on rock faces, and occasionally in leaf litter.

Diet: Small invertebrates, crayfish, and other salamanders.

Breeding information: Mating occurs in late summer and fall resulting in eggs being laid in spring and summer. An average of 45 eggs are deposited under rocks in flowing water and the clutch is then guarded by the female. Hatching occurs in July through September.

Status in Tennessee: Black-bellied Salamanders are abundant across their range in TN; however they are threatened by stream pollution from mining and clearcut timber practices and over-collection for fish bait.  In 1994, TWRA listed the Black-bellied Salamander as "In Need of Management."
