Earless lizards have no external ear openings. This seems to be an adaptation so they don't have to worry about getting sand in their ears when they burrow in to escape. In the Tucson area, these lizards are remarkably similar in appearance and behavior to the zebra-tailed lizards, but occupy a different vertical niche: zebra-tailed lizards abound on the desert floor, whereas these earless lizards live higher, up in the foothills.

On an overcast afternoon in the monsoon season not too many lizards were out and about in the gorgeous red rock desert of Sedona, but we saw a few of these earless lizards strutting their stuff. Their stuff generally consisted of wagging the tail above the body, then dashing twenty yards away in half an instant. Fortunately, I was able to sneak up on a couple of them for these close-ups.
