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.
