About Gerrhosaurus flavigularis Wiegmann, 1828
Gerrhosaurus flavigularis Wiegmann, 1828 is a ground-dwelling, burrowing lizard species. Most individuals are greenish-grey or brownish, with a yellow (and occasionally red) throat, and often have a narrow stripe running down each side of the body. This species is heavily armored, with hard body plates and head shields that are fused to the skull. Its tail typically makes up about two-thirds of its total body length. It has well-developed limbs, and its four five-toed feet are not specifically adapted for digging. Mating for these lizards occurs during the summer. During the mating season, male individuals' heads change color to red, yellow, or even pale light blue. This species was first formally described in 1828 by Wiegmann. Wiegmann’s description was based on specimens held at the Natural History Museum in Berlin, which had been collected in South Africa by Ludwig Krebs.
