Grévy's zebra
The Grévy's zebra is the largest of all wild equines. It is from head to tail with a tail, and stands high at the withers. These zebras weigh . Grévy's zebra differs from the other two zebras in its more primitive characteristics. It is particularly mule-like in appearance; the head is large, long, and narrow with elongated nostril openings; the ears are very large, rounded, and conical and the neck is short but thick. The zebra's muzzle is ash-grey to black in colour with the lips having whiskers. The mane is tall and erect; juveniles have a mane that extends to the length of the back and shortens as they reach adulthood.
Zebra-tailed lizard
Zebra-tailed lizards are diurnal and alert. They rise early and are active in all but the hottest weather. During the hottest times of day, lizards may stand alternately on two legs, switching to the opposite two as needed in a kind of dance. When threatened they will run swiftly with their toes curled up and tails raised over their backs exposing the stripes. When stopped, they wag their curled tails side-to-side to distract predators. They can even run on their hind legs for short distances. In areas of creosote scrub this lizard seems to reach highest densities, around 4.8 to 6.0 individuals per acre (600 to 800 m² per lizard). This lizard burrows into fine sand for retreat at night and usually seeks day shelter in the shade of bushes.
They are also known to burrow under sand for safety when being chased by predators.
