Long-eared Hedgehog (Hemiechinus auritus) lives in desert and grasslands across Central and North Asia. It feeds on insects and fruits. Its conservation status is Least Concern.
Fascinating facts about the Long-eared Hedgehog
- Their ears stretch 30-45 mm beyond the nearest spine, making them longer than half the head length and acting like built-in radiators. In the scorching desert, these oversized ears dump excess heat, letting the hedgehog stay cool while hunting at night. This adaptation shows how a simple body part can become a vital climate-control system, letting the species thrive where many mammals would overheat.
- Measuring just 120-270 mm from snout to rump and weighing 250-400 g (average 342 g), this hedgehog is the smallest Middle Eastern species and can sprint faster than its European cousin. Its compact size and light weight let it outrun predators rather than curl into a ball, a rare strategy among spiny mammals that highlights the trade-off between armor and speed in harsh habitats.
- Females give birth after a 35-42 day gestation to 2-3 pups, each born with barely any spines; within five hours the spines double in size, and by two weeks the young are fully covered. This rapid spine development, noted as both a doubling and a quadrupling in length within hours, equips newborns quickly with protection, illustrating an evolutionary shortcut that balances vulnerability at birth with immediate defense.
- In the wild, insects make up 70 % of its meals, with beetles (30 %), caterpillars (25 %) and earthworms (11 %) leading the menu; bird eggs add another 10 %. Slugs and snails, often assumed to dominate hedgehog diets, actually provide only about 5 %.
- A single night can see a long-eared hedgehog covering up to 9 km in search of food, yet its longest recorded hibernation lasts just 40 days, sometimes in summer or winter.

About the Long-eared Hedgehog
In the arid landscapes of the desert, a diminutive yet fascinating creature emerges under the cover of darkness, its long ears twitching with an almost comical sensitivity as it snuffles out a nocturnal feast. The long-eared hedgehog moves with a curious, ambling gait, its spiny coat glistening in the moonlight as it roots out insects and fruits with an industrious intensity. With its endearingly oversized ears and prickly, defensive armor, this small mammal is a charming embodiment of the resourceful, adaptable spirit that thrives in the harshest of environments.
