Physical appearance

Similar to the other jerboas in the genera Allactaga and Scarturus, the four-toed jerboa are small hopping rodents with large ears and a long tail, with a black band near the white, feathery tip. The tail assists and serves as support when the jerboa is standing upright. [2] 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 extra digit is smaller in size and nonfunctional compared to the other three digits. [4]

Nutrition

Emerging at night, the four-toed jerboa eats grass, leaves, and soft seeds. [5] The low crown molars and soft palates help the four-toed jerboa chew plant material and seeds. [6]

The four-toed jerboa is a host of the acanthocephalan intestinal parasite Moniliformis aegyptiacus . [7]

Conservation status

The four-toed jerboa was listed as on the IUCN Red List of Threatened Species. They are at very high risk of extinction due to habitat loss and restricted range.

Dipodoidea is a superfamily of rodents, also known as dipodoids, found across the Northern Hemisphere. This superfamily includes over 50 species among the 16 genera in 3 families. They include the jerboas, jumping mice, and birch mice. Different species are found in grassland, deserts, and forests. They are all capable of saltation, a feature that is most highly evolved in the desert-dwelling jerboas.

<i>Allactaga</i> Genus of mammals

The genus Allactaga contains the five-toed jerboas of Asia. They are small mammals belonging to the order of rodents. They are characteristically known as the hopping rodents of the desert and semi-arid regions. They have long hind feet, short forelimbs, and walk upright. They have large ears in comparison to their body size and a large tail. The tail assists and serves as support when the jerboa is standing upright. The jerboa body length ranges from 5–15 cm and has a tail ranging from 7–25 cm. The "forelimbs of the jerboa serve as a pair of hands for feeding, grooming, etc." Jerboas use their nose to burrow and push the dirt when looking for food. The male jerboa is usually larger in size and weight in comparison to the female jerboa. The pelt of the jerboa is either silky or velvety in texture and light in color, the coloration helps camouflage into surroundings to avoid predators. All members of the genus have five toes.
