Listing Status

  • FL Status: Federally-designated Threatened
  • FNAI Ranks: G4T2/S2 (Globally: Apparently Secure, Sub sp. Imperiled/State: Imperiled)
  • IUCN Status: Not ranked


The bluetail mole skink is a small lizard that can reach five inches (12.7 centimeters) in length.  This species has a brownish body with a blue tail, which may become pink or orange when an individual gets older or when the tail is regenerated.  Bluetail mole skinks have small legs with five toes per foot, and light colored lines on its upper sides that diverge posteriorly (lines branch off from one point on the back).  Breeding males may develop orange sides in late winter (Florida Natural Areas Inventory 2001). 


The diet of the bluetail mole skink primarily consists of roaches, crickets, and spiders (Christman 1992). 

Little is known about the reproduction of the bluetail mole skink.  Reproduction is thought to be similar to that of the Peninsula mole skink (E.e. onocrepis) (Mount 1963). Females may lay three to seven eggs in a nesting cavity that is less than 11.8 inches (30 centimeters) below the surface. Total incubation time for the eggs is 31-51 days (U.S. Fish & Wildlife Service 1999).

Because bluetail mole skinks need loose sand for burrowing, they inhabit sandhill and xeric hammocks, oak and sand pine scrubs, and turkey oak barrens. In Florida, bluetail mole skinks are found in Highlands, Polk, and Osceola counties along the Lake Wales Ridge (Florida Natural Areas Inventory 2001).


Habitat loss is the main threat to the bluetail mole skink (U.S. Fish & Wildlife Service 1999). Xeric habitat has suffered tremendous losses due to agricultural, residential, and commercial development (Florida Natural Areas Inventory 2001). The limited range of the bluetail mole skink makes it vulnerable to natural or environmental catastrophes. 

Conservation and Management

The bluetail mole skink is protected as a Threatened species by the Federal Endangered Species Act and as a Federally-designated Threatened species by Florida’s Endangered and Threatened Species Rule.
