| Description |
| Size |
| 2.5 - 4 inches from snout to vent (6 - 10 cm), up to almost 9 inches including tail. |
| Appearance |
A pale thin lizard with very long legs and a long flat tail with black crossbars.
Gray or light brown above with light spots and paired dark blotches, which are more distinct on females. As with many lizards, the coloring is darker during lower temperatures, and lighter with very high temperatures.
Dark crossbars or bands on the tail become very distinct black and white underneath This black and white zebra-like pattern gives this lizard its name.
There is pale yellow and orange coloring on the sides. Males have two dark bars and develop a patch of blue-green coloring on the sides of the mid belly during the breeding season, which is visible when viewed from the side. Dark belly markings are faint or absent on females. Scales are granular. |
| Behavior |
Diurnal. Tolerant of high temperatures. Often seen basking on rocks, even on extremely hot afternoons.
Capable of running very fast (possibly the fastest lizard in the desert) facilitated by long legs and streamlined body. After speeding away, this lizard sometimes stops far ahead in the open, but it will also run to the far side of a bush, out of view, or into a bush or burrow for protection. Before running, a lizard may curl the tail up towards the back, exposing the black and white bars, and wag it nervously wag, then continue this behavior while running and after stopping. This tail display tactic concentrates a predator's attention on the tail, which, if attacked and broken off, can grow back.
A countersunk lower jaw makes it easier for this lizard to burrow into loose or sandy soil to rest. |
| Diet |
| Small invertebrates such as insects and spiders, small lizards, occasional plant material. |
| Reproduction |
| Mates in Spring, lays eggs June - August. |
| Range |
This subspecies occurs in Nevada not far from the California border north of Honey Lake, where it might occur in washes along the border near Smoke Creek.
C. draconoides ranges throughout the Mojave and Colorado Deserts up to the desert slopes of the Peninsular and Transverse Mountains, and from the Owens Valley north along the eastern edge of the Sierra Nevada Mountains. Found on the coastal slopes of the mountains at San Jacinto Wash and Cajon Wash. Ranges outside California north into northern Nevada, east into extreme southwest Utah, south through Arizona and extreme southwest New Mexico, to Baja California and the west coast of Mexico. |
| Habitat |
| Open sandy desert washes, desert pavement, and hard pan, with scant widely-spaced vegetation and open areas. Sometimes found in wind-blown sand dunes near hard-packed ground. |
| Taxonomic Comments |
| Subspecies of Callisaurus draconoides are not universally recognized. Many herpetologists recognize three occuring in the United States - C. d. rhodostictus, C. d. myurus - Northern Zebra-tailed Lizard, and C. d. ventralis - Eastern (or Arizona) Zebra-tailed Lizard. Others classify this lizard as Callisaurus draconoides draconoides - Common Zebra-tailed Lizard. |
