Xerocole

A fennec fox standing around in tall grass.
The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area.[1]

A xerocole (from Greek xēros /ˈzɪrs/ 'dry', and Latin col(ere) 'to inhabit'),[2][3][4] is a general term referring to any animal that is adapted to live in a desert. The main challenges xerocoles must overcome are lack of water and excessive heat. To conserve water they avoid evaporation and concentrate excretions (i.e. urine and feces).[1] Some are so adept at conserving water or obtaining it from food that they do not need to drink at all. To escape the desert heat, xerocoles tend to be either nocturnal or crepuscular (most active at dawn and dusk).
