The long-eared jerboa is a small rodent with very long ears, larger than its head. It lives in the deserts of Central Asia, jumps on strong hind legs, and is active only at night.
The long-eared jerboa differs from other jerboas with its enormous ears, longer than its head. It helps maintain balance in the desert food chain by eating insects and serving as prey for foxes and owls.
