It is a pale, sandy-colored animal. The black eartips present on most hares are lacking and white extends from the undersurface well up its sides. Antelope jackrabbits rarely drink water. The litter size varies from 1 to 5. The age of maturity is uncertain, but females probably breed within a year of birth.
Breeding continues year round.
Several litters are born each year, each of which contain 2-4 individuals. The antelope jackrabbit is nocturnal and feeds mainly in the evening and early morning. They do not dig or occupy burrows, but rather depend on their strong running skills when in danger. The antelope jackrabbit is unusual in that it can flash signals like the antelope, by shifting the white hairs on its rump. These signals are flashed when the antelope jackrabbit is running away from predators.
