Bat-eared foxes have large, wide ears, a short narrow mouth and long, jackal-like legs. This fox is easily recognizable by its large ears, which are 13 cm (5 inches) in length. The ears are full of blood vessels that shed heat and help keep the fox cool; they also give the animal a very good sense of hearing. The bat-eared fox generally live in short-grass prairies and arid grasslands and are only found in Africa. Two populations are known, one from Ethiopia and southern Sudan to Tanzania; the other from southern Angola and Rhodesia to South Africa. Bat-eared foxes utilize lairs dug by themselves for protection from severe temperatures and winds. Unlike most mammals of the canid family, the bat-eared fox favors a diet of insects, with a penchant for termites and grasshoppers. After a gestation period of two months, the female gives birth to one to five cubs.
