Description

Adult Bermuda skinks (also known as "rock lizards") have dark brown or black backs and are pinkish or light gray on the underside. Juveniles are lighter in color and have black stripes running along the sides of their bodies, which fade with age. Females are thought to retain the stripes longer than males. Adult males have larger heads. Hatchlings have bright blue tails. All have salmon orange cheeks and throat. The Bermuda skink lives predominantly in rocky coastal areas. They feed on small

Distribution

The species occurs only in Bermuda, and exists mainly on some of the smaller islands and nature reserves on the mainland, where the populations are fragmented into isolated pockets.
