### Identification The Giant Girdled Lizard, or Sungazer, looks like a prehistoric relic carved from the earth. Reaching up to 15 inches (40cm), it is the largest of the girdled lizards. Its body is encased in heavy, keeled, straw-colored scales that terminate in sharp, obsidian-tipped points. To distinguish it from its smaller cousins, look at the head: four massive, backward-pointing occipital spines form a formidable crown. Unlike the rock-dwelling *Cordylus* species, the Sungazer has a flattened profile and heavily armored limbs designed for life on the open plains.
### Habitat & Range This specialist is endemic to a tiny sliver of the South African Highveld, primarily within the Free State and Mpumalanga provinces. You won't find them on rocky outcrops; instead, they inhabit high-altitude, primary *Themeda* grasslands. They are remarkably picky, requiring deep, black "turf" clay soils that allow them to excavate permanent burrows without the tunnels collapsing.
### Behaviour The most iconic sight for a naturalist is the "sentinel" pose. The lizard sits at its burrow entrance with its forebody propped high, staring fixedly at the sun—a behavior that earned it the name "Sungazer." They live in loose colonies, yet each adult maintains its own burrow. They are incredibly shy; a heavy footfall or a passing shadow will send them reversing into their tunnels, using their spiny tails to wedge themselves immovably against the walls.
### Diet Sungazers are patient sit-and-wait predators. Their diet consists almost entirely of invertebrates, with a particular preference for beetles, millipedes, and ants. When a target wanders close to the burrow entrance, the lizard lunges with surprising speed, crushing the chitinous prey with powerful jaws.
### Fascinating Fact In 2011, taxonomists officially moved this species from the genus *Cordylus* to a new genus named *Smaug*. This was a direct homage to the formidable dragon in J.R.R. Tolkien’s *The Hobbit*, as both the fictional dragon and this lizard share a penchant for underground "lairs" and a heavily armored, spike-covered appearance.
