are found in arid deserts and steppes, and they commonly burrow under small bushes. They may also rest by day under rocks, rock heaps or hollows.
Length of the head and body ofis approximately 120-270mm, and the tail is 10-50mm long. The spines are banded with dark brown and white, and the underparts of the hedgehog are whitish. The ears are much larger than those of other hedgehogs (longer than half the length of it head) and are considered a development for heat radiation in the desert. Long-eared desert hedgehogs also have acute senses of hearing and smell, which they use to locate food and detect predators
breeds only once a year, generally between July and September, and females have between 1-4 offspring per litter. Gestation is 35-42 days; the young's eyes open after one week, and baby hedgehogs eat solid food after three weeks. Baby hedgehogs are born naked except for sparsely scattered spines, which are very soft. The spines quadruple in length within 5 hours after birth and after 2 weeks, the babies are fully covered with them. Very little is known about their life cycle (such as weaning, age at sexual maturity or life span in the wild).
Althoughpossesses sharp spines on its back that protect it from predators, it is also able to run very fast. Long-eared hedgehogs dig their own burrows (usually under bushes), which are approximately 45 cm long and have a single opening. They have also been observed to use the burrows of other small mammals. Hedgehogs are solitary and sleep rolled up individually in their burrows, except during the breeding season when females keep offspring with them. Long-eared hedgehogs are nocturnal, and they may wander up to 9 km a night in search of food. They often enter periods of torpor in the summer and in some areas they hibernate in the winter. Presence of the spines on hedgehogs have often led people to wonder how mating is accomplished. In , the male copulates by standing almost vertically on his hind legs while the female lays on her ventrum with hind legs extended on the ground.
The long-eared desert hedgehog is omnivorous but feeds mainly on small invertebrates and insects. Favorite foods include grasshoppers, beetles, and other insects. They also consume eggs, fruit, vegetables and even small vertebrates such as lizards and snakes. They are remarkably resistant to scarcity of food and water; in the laboratory they have survived as long as ten weeks without food and water.
Hemiechinus auratus is considered beneficial because it eats many harmful insects, including termites and even scorpions. It does not damage agricultural crops since it lives largely in waste land on the edge of cultivation or in open desert.
Little is known about the occurrence of, but they appear to be plentiful in their ranges.
Long-eared desert hedgehogs are curious animals and are easily tamed and kept in captivity.

Found in coastal areas between 30 and 40 degrees latitude, in areas with a Mediterranean climate. Vegetation is dominated by stands of dense, spiny shrubs with tough (hard or waxy) evergreen leaves. May be maintained by periodic fire. In South America it includes the scrub ecotone between forest and paramo.

in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
