The Aarvark (Orycteropus afer) ("Digging foot") is a medium-sized, burrowing, nocturnal mammal native to Africa. It is sometimes called "antbear", "anteater", "Cape anteater" (after the Cape of Good Hope), "earth hog" or "earth pig". The name comes from the Afrikaans/Dutch for "earth pig" (aarde earth, varken pig), because early settlers from Europe thought it resembled a domesticated pig. However, the aardvark is not closely related to the pig; rather, it is the sole recent representative of the obscure mammalian order Tubulidentata, in which it is usually considered to form a single variable species of the genus Orycteropus, coextensive with the family Orycteropodidae. Nor is the aardvark closely related to the South American anteater, despite sharing some characteristics and a superficial resemblance. The closest living relatives of the aardvark are the elephant shrews, along with the sirenians, hyraxes, tenrecs and elephants.
