Fennec foxes are small (weigh up to 3 pounds) nocturnal mammals native to the dry desert regions of northern Africa. They have distinctive large ears that help them radiate heat and keep cool in hot climates. Like most foxes, fennec foxes, dig burrows in which they sleep, raise their young, and retreat from the heat of the day. They are social and live in family groups of up to ten individuals. Fennec foxes eat a varied diet that includes insects, birds, eggs, fruit, grasses, and plants. They are well adapted to desert climates and can survive for long periods without drinking water. Average life span in the wild is unknown, but Fennec foxes can live up to 16 years in captivity.
