The Long-eared Jerboa's head and body length measures 70 mm (2.8 in) to 90 mm (3.5 in) while its tail is double this size, between 150 mm (5.9 in) and 163 mm (6.4 in). Like its disproportionately long tail, its hind feet are also large, helping it to jump high, measuring between 40 mm (1.6 in) and 46 mm (1.8 in). It weighs 23.7 g (0.84 oz) to 37.8 g (1.33 oz).
Jerboas are small jumping rodents that resemble mice with long tufted tails and very long hindlegs. The long-eared jerboa can be distinguished from other jerboas by its enormous ears, which are about a third larger than its head. Very little is known about this species. Other jerboas are primarily nocturnal, spending the hours of daylight in underground burrows, which they dig themselves. The species is thought to be declining as a result of human disturbance of its habitat.
