Knowra Antelope jackrabbit Antelope jackrabbit The antelope jackrabbit is a large hare native to the deserts and scrublands of the southwestern United States and northwestern Mexico, distinguished by exceptionally long ears and a pale underside.
Lepus : Lepus is a genus of hares that includes jackrabbits and true hares. The antelope jackrabbit belongs to this genus of long-legged, fast-running hares.
Thermoregulation : Thermoregulation is the control of an animal's body temperature through physiological and behavioral processes. Blood flow through its large, thinly furred ears helps release excess body heat.
Sonoran Desert : The Sonoran Desert is a hot desert spanning parts of Arizona, California, and northwestern Mexico. This desert forms a major part of the antelope jackrabbit's geographic range.
Black-tailed jackrabbit : The black-tailed jackrabbit is a widespread North American hare with a black stripe along its tail. It overlaps geographically and is smaller, with a conspicuously dark tail.
Sonoran Desert scrub : Sonoran Desert scrub is a vegetation community dominated by drought-tolerant shrubs, cacti, and scattered trees. This vegetation is characteristic of parts of the species' western range.
Hare : Hares are fast-running mammals in the genus Lepus, generally born furred and with open eyes. This broader group distinguishes the antelope jackrabbit from rabbits in other genera.
Rabbit ear : A rabbit ear is a mobile sensory structure used for hearing and, in many species, heat exchange. The antelope jackrabbit's exceptionally large ears serve both heat-dissipation and sound-detection functions.
Chihuahuan Desert : The Chihuahuan Desert is a high-elevation desert covering parts of the southwestern United States and northern Mexico. Its grasslands and scrublands provide habitat in the species' eastern range.
White-tailed jackrabbit : The white-tailed jackrabbit is a large hare of western North America, often associated with colder and higher-elevation habitats. It is another large jackrabbit, but its range and seasonal coloration differ.
Arizona : Arizona is a southwestern U.S. state with extensive desert and scrubland regions. The state contains substantial habitat for the antelope jackrabbit.
