The Gerrhosaurus are native to southern and eastern Africa. There are six species found in dry, rocky semi-open habitats. Frequently found in termite mounds.
The species range in size from 40-70 cm (16-28"). Their powerfully-built bodies are only slightly flattened and are supported on relatively delicate-looking legs, much like our own Alligator lizards (Gerrhonotus). The neck is not well differentiated from the head. The tail is typically twice the length of the body.
Scales are evenly arrayed in lines down and around the body. Dorsal scales are keeled while the ventral scales are smooth; little overlapping. Colors are various shades of brown with some lighter longitudinal stripes.
A fold of skin is generally noted running laterally along the length of the body - this allows for expansion.
The plateds become rather tame fairly quickly. While they appear cumbersome and slow, they are capable of movement and, when acclimated, feed well. Some may eventually take small amounts of dog food mixed in their salad which can be used as an occasional supplement to whole prey.
G. flavigularis. Yellow-throated plated lizard. Southern and eastern Africa. 45 cm (18"). Back is brown with 2 lighter-edged longitudinal stripes above sides. Belly is white; throat, chest, neck and sides of head yellow to orange when in breeding season.
G. major. Tawny Plated Lizard. Eastern and southeastern Africa. In excess of 50 cm (20"). Yellow to dark brown with or without black longitudinal stripes. Large component of this species is plants. Usually only 2 eggs laid.
G. validus. Giant Plated Lizard. Southern Africa north to Angola and Mozambique. Almost 70 cm (28"). Blackish brown with narrow bright yellow vertical stripes. Eats a large amount of plant material. Largest lizard in the genus.
G. nigrolineatus. Black-lined Plated lizard. Central to southern Africa. 45 cm (18"). Dark brown to black with light longitudinal stripes. More agile than the other species. Likes to dig.
