The aardvark ( ARD-vark; Orycteropus afer) is a medium-sized, burrowing, nocturnal mammal native to Africa. The aardvark is the only living member of the genus Orycteropus, the family Orycteropodidae and the order Tubulidentata. It has a long proboscis, similar to a pig's snout, which is used to sniff out food. The aardvark is an afrotherian, a clade that also includes elephants, manatees, and hyraxes. It is found over much of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeder, the aardvark subsists on ants and termites by using its sharp claws and powerful legs to dig the insects out of their hills. Aardvarks also dig to create burrows in which to live and rear their young.
