The blacktail jack rabbit, Lepus californicus, is a hare that grows from 18 to 25 inches long and weighs 4 to 8 lbs. Its fur is gray on its sides, blackish to gray on its back and white on its underside. It also has black-tipped ears that range from 4 to 7 inches long. It rests during the day in forms, which are depressions they make in the shade of plants. Blacktail jackrabbits forage at night, and may come together in large groups when they do.
The blacktailed jac rabbit's diet tends to vary with the season. It eats hay, buds, leaves of woody plants, bark, perennial grasses, green rabbitbrush, crested wheatgrass, cheatgrass and winterfat.
The desert tortoise, Gopherus agassizii, can grow up to 14 inches long, has a gray or brown rounded shell top, or carapace, and a yellow underside, or plastron. It is toothless, as are all turtles. It lives in burrows.
The diet of the desert tortoise changes seasonally. It eats fresh and dry grasses, wild flowers and cactus pads.
The desert cottontail, Sylvilagus audubonii, is a mostly gray and pale yellow-brown rabbit with a more reddish back and a white stomach. It grows to be 2 lbs., and like the blacktail jackrabbit, it rests in forms during the day. The ears of the desert cottontail are long for a cottontail species. It prefers bushy areas that have burrows of other animals, which serve as places of refuge when it is escaping something.
In the fall and the winter, the rabbit eats twigs and bark. In the spring and summer, it eats grass and other plants.
Also known as the pronghorn or Antilocapra Americana, the pronghorn antelope resembles a deer. It has two toes on each foot and black, pronged horns. Females weigh around 105 lbs. and males weigh around 120 lbs.

The diet of the pronghorn antelope varies by season. Its diet includes broom weed, groundswell, sagebrush, cutleaf daisy, stickleaf, goatweed, paper flower, Mexican tea, sacahuiste and javelina bush.
