Cryptoblepharus egeriae

These lizards are usually 2-3 inches long, but may reach 5 to 6 inches in length. They are not especially agressive, but will bite if provoked. The bite is not very painful, even to children, which may find great amusement with the spectacle of lizard dangling from their forefinger. Some species have are dark brown to black in color, with 5 yellow stripes down their backs, which provides an alternate name Five-line racer.
