### Identification The Rainbow Skink (*Trachylepis margaritifera*) is a masterclass in reptilian color. Reaching lengths of up to 20cm, it possesses the sleek, streamlined body typical of the *Mabuya* group. Juveniles and females are the most striking: five neon-yellow stripes race down a jet-black torso, terminating in an electric-blue tail that seems to glow. As males mature, they trade these stripes for a "rainbow" wash—an olive-brown back, vibrant orange-red flanks, and a pearlescent, stippled throat.
Field Mark:
To distinguish it from the nearly identical Five-lined Skink (*T. quinquetaeniata*), look closely at the labials (lips). *T. margaritifera* usually features distinct white spots on these scales, and the male’s orange coloration is typically more intense and uniform along the sides.
### Habitat & Range This species is a specialist of the kopje (granite outcrops) across Eastern and Southern Africa, from KwaZulu-Natal up through Zimbabwe and Malawi. They are "lithophilous"—rock-loving—and are rarely found far from a sun-warmed stone surface. While they favor rocky savannas and woodland fringes, they are remarkably bold and have successfully moved into human suburbs, where they treat garden walls and brick foundations as artificial cliffs.
### Behaviour Rainbow Skinks are quintessential "sun-worshippers." You will find them flattened against rocks in the mid-morning heat, absorbing thermal energy before becoming a blur of motion. They are highly territorial; a dominant male will perch on the highest point of a boulder, performing vigorous "push-ups" to warn off rivals. When threatened, they don't just run; they dive into narrow rock crevices, using their smooth scales to wedge themselves in where predators cannot reach.
### Diet These are active, visual hunters. They spend their days patrolling rock faces for beetles, grasshoppers, and termites. Because of their speed, they can even snatch flies right out of the air. In garden settings, they are opportunistic, occasionally feeding on fallen soft fruits or small invertebrates attracted to outdoor lights.
### Fascinating Fact While many lizards lay eggs and leave them to the elements, the Rainbow Skink is viviparous. The female gives birth to up to ten fully-formed, independent young. This "live-birth" strategy is a brilliant adaptation for life on rocky outcrops, where finding enough soil to bury and protect eggs can be a life-threatening challenge.
