The (American) five-lined skink (Plestiodon fasciatus) is a species of lizard endemic to North America. It is one of the most common lizards in the eastern U.S. The American five-lined skink is small to medium-sized, growing to about 12.5 to 21.5 centimetres (4.9 to 8.5 in) total length. Young five-lined skinks are dark brown to black with five distinctive white to yellowish stripes running along the body and a bright blue tail. The blue color fades to light blue with age, and the stripes also may slowly disappear. The dark brown color fades, too, and older individuals are often uniformly brownish.
