Pseudocordylus melanotus

### **Common Crag Lizard (*Pseudocordylus melanotus*)**

Identification

This robust, medium-sized lizard is a master of the "flat look." Reaching up to 30cm in total length, its body is remarkably dorso-ventrally compressed—an adaptation for sliding into the narrowest rock fissures. Look for a dark, often black, broad band running down the spine (hence *melanotus*, meaning "black-backed"). While females and juveniles are cryptically mottled in browns and greys to mimic lichen-splattered sandstone, breeding males are a riot of color. They sport citrus-bright flanks of lemon yellow or deep orange that contrast sharply against their dark backs. Unlike the heavily armored *Cordylus* genus, the Common Crag Lizard has finer, granular scales on its back, though its tail remains ringed with protective spines.

Habitat & Range

True to their name, these lizards are denizens of the high-altitude "krantzes" (cliffs) and rocky outcrops of Southern Africa. They are most abundant in the Drakensberg Mountains and the Highveld, spanning South Africa, Lesotho, and Eswatini. You’ll find them at elevations ranging from 1,200 to over 3,000 meters, typically perched on north-facing rock faces that catch the first rays of the morning sun.

Behaviour

In the field, you’ll likely spot a dominant male "sentinel" perched atop a prominent boulder. They are heliothermic sun-worshippers, but they are incredibly wary; a passing shadow will send them scurrying into a crevice with lightning speed. During the breeding season, males become highly territorial, using vigorous head-bobbing and displays of their colorful flanks to ward off rivals. They are viviparous, giving birth to 2–4 live young in late summer.

Diet

These are opportunistic ambush predators. They sit motionless, scanning for movement before lunging at beetles, grasshoppers, and crickets. Large adults have been known to diversify their palate with smaller lizards or occasional floral snacks like succulent leaves and petals.

Fascinating Fact

The Common Crag Lizard employs a "pneumatic" defense system. When threatened inside a rock crack, it doesn't just hide; it gulps air to inflate its lungs, wedging its flattened body and spiny tail so firmly against the rock walls that it becomes physically impossible for a predator to pull it out!
