Overview
The Southeastern Five-lined Skink (Plestiodon inexpectatus) is an agile, smooth-scaled woodland lizard native to the sandy pine ridges and coastal hammocks of the American Southeast. Famous for its dazzling juveniles that sport an electric neon-blue tail, this versatile skink is often found basking on sunlit pine stumps or climbing high into tree trunks, tolerating much drier, sandier habitats than its close relative, the common five-lined skink.
Biology and Physical Characteristics
Plestiodon inexpectatus possesses a sleek, torpedo-like body covered in glossy, overlapping cycloid scales. Juveniles and young adults have a pitch-black body boldly striped with five narrow, yellowish-white longitudinal lines that converge at the snout, terminating in an eye-popping, cobalt-blue tail. Adult males fade with age to a uniform olive-brown, developing an enlarged, reddish-orange head during the spring breeding season.
Behavior and Ecology
More arboreal and drought-tolerant than other eastern skinks, the Southeastern Five-lined Skink frequently climbs dead standing pines, utility poles, and saw palmetto trunks up to several meters above the ground to hunt spiders and avoid terrestrial predators. If seized by a bird or raccoon, the lizard readily detaches its bright blue tail (caudal autotomy); the severed tail thrashes violently for minutes to distract the predator while the lizard slips away.
Conservation and Human Impact
Classified as Least Concern by the IUCN, Plestiodon inexpectatus remains common throughout Florida and the southeastern coastal plain. It is resilient in managed longleaf pine savannas, benefiting from periodic controlled burns that maintain open sunny basking sites and abundant fallen deadwood habitat.
Interesting Factoid
A juvenile Southeastern Five-lined Skink’s electric-blue tail glows brightly in ultraviolet light, drawing predatory attacks away from the lizard’s vital organs toward a tail that can easily snap off and regrow completely.
