The Long-Eared Jerboa

The long-eared jerboa (Euchoreutes naso) is a nocturnal mouse-like rodent with a long tail, long hind legs for jumping, and exceptionally large ears. It is distinct enough that authorities consider it to be the only member of both its genus, Euchoreutes, and subfamily, Euchoreutinae. They are found in the Palearctic ecozone in southern Mongolia to the Takla-Makan Desert, Mengxin, Aerijin Mountain, and Qing-Zang Plateau regions of northwestern China. The long-eared jerboa’s fur is reddish yellow to pale russet with white underparts. Very little is known about the species. The long-eared jerboa’s head and body length measure 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 162 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 24 g (0.85 oz) to 38 g (1.3 oz). Their diet consists of insects and they use sound to locate and capture them by performing fast leaps into the air. Credit: Wikipedia.
