Coal Skink

Coal Skink
Plestiodon anthracinus

Two subspecies occur in TN; Southern Coal Skink (P. a. pluvialis) is found next to the Tennessee River in western part of state and Northern Coal Skink (P. a. anthracinus) exists in Great Smoky Mountains National Park.

Description: A medium-sized lizard (5.0 to 7.0 inches in length) with smooth, shiny scales and short legs. Back color ranges from olive-gray to brown. A wide dark brown or black lateral stripe extends from the head onto the tail along each side of body, bordered by a thin light line above and below. Belly is gray or bluish-gray. Males have dark orange or reddish tint on sides of the head during breeding season. Adult females are slightly larger than males.

Similar Species: Common Five-lined and Southeastern Five-lined Skinks have stripe down the center of the back.

Habitat: Prefers open, moist forests near streams, river, or sloughs. Also, occurs on rocky hillsides and near springs.

Diet: Variety of small insects and spiders.

Breeding information: Courtship and breeding occurs in spring. Female lays 4-9 eggs in rotten logs or moist soil, guarding them until they hatch in the summer.

Status in Tennessee: Uncommon within its restricted range. The Coal Skink is listed as “In Need of Management” by TWRA and considered very rare and imperiled by Tennessee Department of Environment and Conservation.

Fun Facts:

  • As with all skinks, the Coal Skink can quickly and easily break off its tail if grasped by a predator or human. A new tail will regenerate.

Best places to see in Tennessee: Open forests next to Tennessee River in west TN.
