How the desert-dwelling jerboa masters the art of the three-metre leap

Nature · Published 3 October 2026 Swipe more like this →

In short: These mouselike rodents are master escape artists, using specialized anatomy to launch themselves three metres in a single bound. With long tails for balance and fused leg bones for leverage, the jerboa is a desert specialist that has evolved to survive in some of the world's harshest, most open environments.

Jerboas are a diverse group of 33 species belonging to the family Dipodidae, found across the deserts and steppes of Asia, northern Africa, and eastern Europe. Their evolutionary history stretches back to the Middle Miocene Epoch, between 16.4 million and 11.2 million years ago. Despite their small size—with bodies ranging from 5 to 15 cm—they possess remarkable physical adaptations for life in arid regions. Their fur is typically sand-coloured to match their habitat, and some species have developed specialized hair and skin folds to protect their ears and noses from blowing sand.

The jerboa's most striking feature is its locomotion. Unlike many other hopping mammals, jerboas are obligate bipeds, moving almost exclusively on their hind legs. Their anatomy is highly specialized for this: they possess a fused metatarsal bone known as a cannon bone, which provides the leverage necessary for high-speed, erratic jumping. When threatened, they can leap up to 3 metres, using sharp turns and vertical jumps to confuse predators. Their long, tufted tails serve as essential counterweights for balance during these maneuvers and as props when the animals stand upright.

Survival in the desert requires sophisticated behavioral adaptations. Jerboas are primarily nocturnal, spending the heat of the day in burrows, sometimes plugging the entrances with soil to retain moisture and exclude hot air. They construct various types of burrows, including temporary shelters for hunting and permanent structures for raising young or hibernating through the winter. While they can drink water in captivity, they typically obtain all necessary moisture from their diet of seeds, succulent plants, and insects. Their ability to thrive in these open, exposed habitats is a testament to their highly evolved, predator-evading movement and efficient resource management.
