The greater Egyptian jerboa (Jaculus orientalis) is a species of rodent in the family Dipodidae. [2] It is found in Algeria, Egypt, Libya, Morocco, Saudi Arabia, Tunisia, and is possibly extinct in the Negev Desert of Israel. Its natural habitats are subtropical or tropical dry shrubland, sandy shores, and arable land.
Jerboas that live in sandy desert environments develop hairs on the bottom of their feet that allow for better traction and grip so that they don't slip in the sand. [ 5 ] Like other bipedal animals, their foramen magnum —the hole at the base of the skull—is forward-shifted, which enhances two-legged locomotion. [ 6 ]
They have long hind feet and short forelegs. [3] The pelt of the four-toed jerboa is velvety in texture and the upper-parts are speckled black and orange, the rump orange, and the sides gray. The four-toed jerboa hind-limbs have one digit less than other jerboas in the subfamily Allactaginae, but one more hind digit than other jerboas. The ...
The lesser Egyptian jerboa can travel long distances in search of food, up to ten kilometres a day, which it easily covers thanks to its large feet and hopping stride; the jerboa is known to leap up to three metres in a single bound. Lesser Egyptian Gerbil from South Yanbu, Saudi Arabia
Kozlov's pygmy jerboa, Salpingotus kozlovi; Subfamily Dipodinae. Tribe Dipodini. Genus Dipus. Northern three-toed jerboa, Dipus sagitta; Genus Eremodipus. Lichtenstein's jerboa, Eremodipus lichtensteini; Genus Jaculus. Blanford's jerboa, Jaculus blanfordi; Lesser Egyptian jerboa, Jaculus jaculus; Greater Egyptian jerboa, Jaculus orientalis
The jerboa body length ranges from 5–15 cm and has a tail ranging from 7–25 cm. [7] The "forelimbs of the jerboa serve as a pair of hands for feeding, grooming, etc." [8] Jerboas use their nose to burrow and push the dirt when looking for food. [9] The male jerboa is usually larger in size and weight in comparison to the female jerboa. [10]

The central toe on the hind foot is the longest and the sole of the foot is haired. The tail is thickened by the adipose tissue beneath the skin and has a flattened, terminal, black bushy section. It can be distinguished from the rather similar thick-tailed three-toed jerboa ( Stylodipus telum ) by the fact that it has premolars in the upper ...
