Jerboas (from Arabic: جربوعjarbūʻ ) are hopping desert rodents found throughout North Africa and Asia,[1] and are members of the family Dipodidae. They tend to live in hot deserts.[1]

When chased, jerboas can run at up to 24 km/h (15 mph).[1] Some species are preyed on by little owls (Athene noctua) in central Asia. Most species of jerboas have excellent hearing that they use to avoid becoming the prey of nocturnal predators. The typical lifespan of a jerboa is around 6 years.[2]


Jerboas, as previously defined, were thought to be paraphyletic, with the jumping mice (Zapodidae) and birch mice (Sminthidae) also classified in the family Dipodidae. However, phylogenetic analysis split all three as distinct families, leaving just the jerboas in Dipodidae and revealing them to be a monophyletic group.[3]

Anatomy and body features

Jerboas look somewhat like miniature kangaroos, and have some external similarities. Both have long hind legs, very short fore legs, and long tails. Jerboas move around in a similar manner to kangaroos, which is by hopping. Like other bipedal animals, their foramen magnum — the hole at the base of the skull — is forward-shifted, which enhances two-legged locomotion.[4] The tail of a jerboa can be longer than its head and body, and white cluster of hair is commonly seen at the end of the tail. Jerboas use their tails to balance when hopping, and as a prop when sitting upright. Jerboa fur is fine, and usually the colour of sand. This colour usually matches the jerboa habitat (an example of cryptic colouration).[1][2] Some species of the jerboa family have long ears like a rabbit, whilst others have ears that are short like those of a mouse or rat.


The bipedal locomotion of jerboas involves hopping, skipping, and running gaits, associated with rapid and frequent, difficult-to-predict changes in speed and direction, facilitating predator evasion relative to quadrupedal locomotion. This may explain why evolution of bipedal locomotion is favored in desert-dwelling rodents that forage in open habitats.[5]

Jerboas are are most active at twilight (crepuscular).[6] During the heat of the day, they shelter in burrows. At night, they leave the burrows due to the cooler temperature of their environment. They dig the entrances to their burrow near plant life, especially along field borders. During the rainy season, they make tunnels in mounds or hills to reduce the risk of flooding. In the summer, jerboas occupying holes plug the entrance to keep out hot air and, some researchers speculate, predators.[1] In most cases, burrows are constructed with an emergency exit that ends just below the surface or opens at the surface but is not strongly obstructed. This allows the jerboa to quickly escape predators.

Related jerboas often create four types of burrows. A temporary, summer day burrow is used for cover while hunting during the daylight. They have a second, temporary burrow used for hunting at night. They also have two permanent burrows: one for summer and one for winter. The permanent summer burrow is actively used throughout the summer and the young are raised there. Jerboas hibernate during the winter and use the permanent winter burrow for this. Temporary burrows are shorter in length than permanent burrows.[2]

Jerboas are solitary creatures. Once they reach adulthood, they usually have their own burrow and search for food on their own. However, occasional "loose colonies" may form, whereby some species of jerboa dig communal burrows that offer extra warmth when it is cold outside.[1]


Most jerboas rely on plant material as the main component of their diet, but they cannot eat hard seeds. Some species opportunistically eat beetles and other insects they come across. Unlike gerbils, jerboas are not known to store their food.[1]

Communication and perception

Many species within the family Dipodidae engage in dust bathing, often a way to use chemical communication. Their keen hearing suggests they may use sounds or vibrations to communicate.[2]


Mating systems of closely related species in the family Dipodidae suggest that they may be polygynous. For some closely related jerboa species, mating usually happens a short time after awaking from winter hibernation. A female breeds twice in the summer, and raises from two to six young. Gestation time is between 25 and 35 days. Little is known about parental investment in long-eared jerboas. Like most mammals, females nurse and care for their young at least until they are weaned.[2]
