6 inches – 9 ½ inches
- As its name implies, this slender animal has six light-colored stripes starting at its head and continuing down along the tail.
- The back color is brown to black. The back scales are small, resulting in a very smooth look.
- The belly has large scales arranged in eight rows.
- Its tail is long (compared to our other lizards, over half its total length).
- The scales on the tail are keeled, giving it a rough feel and appearance.
- Young racerunners resemble adults except that they have bright blue tails.
