Antelope jackrabbit (Lepus alleni). This hare is native to the deserts of north-western Mexico and south-central Arizona,USA. Its ears,which are almost a quarter of its total body length,are vital for temperature regulation. During hot conditions the hare loses heat by holding its ears upright and dilating its blood vessels. When it is cold,it holds its ears close to its body. This jackrabbit is named for the massive antelope- like leaps it can make. Photographed in the Saguaro National Park,Arizona | |
