The aardvark ( ; 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. 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 (myrmecophagy) by using its sharp claws and powerful legs to dig the insects out of their hills, and its long snout to sniff out food. It digs a burrow in which to live and rear its young.

Eye features and retinal photoreceptors of the nocturnal aardvark (Orycteropus afer, Tubulidentata).. The nocturnal aardvark Orycteropus afer is the only extant species in the mammalian order Tubulidentata. Previous studies have claimed that it has an all-rod retina. In the retina of one aardvark, we found rod densities ranging from 124,000/mm² in peripheral retina to 214,000/mm² in central retina; the retina of another aardvark had 163,000 - 245,000 rods/mm². This is moderate in comparison to other nocturnal mammals. With opsin immunolabelling we found that the aardvark also has a small population of cone photoreceptors. Cone densities ranged from about 300 to 1,300/mm² in one animal, and…

Orycteropodidae is a family of afrotherian mammals. Although there are many fossil species, the only species surviving today is the aardvark (Orycteropus afer). Orycteropodidae is recognized as the only family within the order Tubulidentata (from Latin tubulus 'little tube' and dens 'tooth'), referring to the tubule-style teeth, so the two are effectively synonyms.
