Antelope Jackrabbit (Lepus alleni)
The antelope jackrabbit is the largest rabbit in the western hemisphere. They can be distinguished from black-tailed jackrabbits by their larger size, lack of black ear tips, and a broad white patch on their flanks and hindquarters. The antelope jackrabbit is named so because they dodge predators in a manner similar to that of antelope. They are relatively uncommon at Saguaro National Park but can be found in large, sandy washes. Antelope jackrabbits rarely have water available, so they get their moisture from cacti and other plants. They conserve water by resting in the shade during the hottest hours of the day, restricting activities to the cooler times.
