The tiny, mighty Fennec desert fox has adapted to live in the Sahara Desert, one of the most difficult environments on earth. As predators, their huge ears are an auditory advantage.
Great hearing helps them find insects like scorpions at night, as well as small rodents and birds. They also eat seeds, tubers, roots, fruit, and leaves.
At eight inches (20 cm) tall, and only weighing two or three pounds (about 1 kg), their small size–as well as the camouflage afforded by their beige coat–make them effective nocturnal hunters. Large ears also allow body heat to dissipate more readily in the blazing sun of in the African and Arabian Pennisulas.
Family groupings of up to ten live in communal dens to keep cool in the hot desert sun during the day. Father foxes are known to be a great help in raising young. The adult male foxes bring food to the den when the kits are young, and also train them how to hunt.
According to Treehugger.com, this wily desert fox is “is shorter than the average house cat and a fraction of the weight.” The Fennec Fox, along with Blanchard’s Fox, are considered the smallest foxes on earth.
Predators like hawks, jackals, hyena, snakes and wildcats can take advantage of the foxes’ small size—if the foxes don’t manage to escape first by running, or digging a hole. Humans threaten fennec foxes via habitat loss. Man also hunts them, and is known to sell fennec foxes in the exotic pet trade.
Other evolutionary advantages the adorable, amazing, teeny fennec fox have are fur on the pads of their feet that help prevent burns from the desert sand. Also, living without standing water is possible for the species, because they metabolize moisture provided by their prey.
Fennec foxes live up to thirteen years in captivity, or ten years in the wild. Females are ready to mate only during one day annually (between January and April). And each year, two to five kits are born helpless, and blind. Babies are weened at five weeks, and are considered adults at about nine months.
