 of the family Dipodidae, found in arid parts of Asia, N Africa, and SE Europe. Jerboas have extremely long hind feet and short forelegs; they always walk upright or hop like kangaroos. A jerboa can hop faster than a person can run, and a single leap may carry it more than 6 ft (1.8 m). Jerboas have long silky fur, buff colored above and pale below; members of most species have a black face mask and tail tuft. They have large eyes and long ears. The combined head and body length is between 2 and 8 in. (5–20 cm), depending on the species; the tail is usually somewhat longer than the body. When the animal sits, the tail is used as a prop. Solitary, nocturnal animals, with a low tolerance for heat, jerboas spend the day in individual burrows with plugged entrances. In the northern parts of their range they hibernate; some jerboas of the true deserts aestivate. They feed on plant matter, especially seeds, and insects. They do not drink, but survive on water obtained from food or produced by their own metabolism. The similar appearing kangaroo ratkangaroo rat,

The kangaroo rats (Dipodomys), the kangaroo mice (Microdipodops), the pocket mice (Prognathus, Chaetodipus), some jerboas (Car-diocranius, Salpingotus), and gerbils (Gerbillus) are able to live--without losing weight--on a diet of air dry seeds at an atmospheric humidity of 20-30%.

Because they have a greater reserve of water per unit surface area, large animals like the dromedary (Camelus dromedarius), the ass (Equus asinus), the addax (Addax nasomaculatus), the oryxes (Oryx), and the Dorcas gazelle (Gazella dorcas) can resist a given rate of water loss for a longer time than small mammals (such as jerboas and kangaroo rats) without dying.
The interaction of species and habitat emerges from an erratic response of jerboas to habitat.
