The five-toed pygmy jerboa (Cardiocranius paradoxus) is a species of rodent in the family Dipodidae. It is monotypic within the genus Cardiocranius. [2] It is found in China, Kazakhstan, and Mongolia.

Its natural habitat is temperate desert. This species is not well known and its population and conservation status are unresolved.

Cardiocranius paradoxus has adapted to its desert environment by burrowing underground to prevent overheating and promote survival. They use their burrows for food storage and shelter, and, in cold winters, they hibernate in burrows to conserve energy. Burrowing accounts for the five-toed pygmy jerboa's tendency to be nocturnal, as they prefer to forage for food during the night when conditions are less severe. [3]

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.
