The aardvark looks like a cross between a pig and an anteater. Its body is stout with an arched back and is sparsely covered with coarse hairs. The limbs are of moderate length. The front feet have lost the pollex (or 'thumb'), resulting in four toes, while the rear feet have all five toes. Each toe bears a large, robust nail which is somewhat flattened and shovel-like, and appears to be intermediate between a claw and a hoof. The ears are disproportionately long, and the tail is very thick at the base and gradually tapers. The greatly elongated head is set on a short, thick neck, and the end of the snout bears a disc, which houses the nostrils. The mouth is small and tubular, typical of species that feed on termites. The aardvark has a long, thin, snakelike, protruding tongue and elaborate structures supporting a keen sense of smell. An aardvark's weight is typically between 40 and 65 kilograms (88 and 140 lb). An aardvark's length is usually between 1 and 1.3 metres (3.3 and 4.3 ft), and can reach lengths of 2.2 metres (7 ft 3 in) when its tail (which can be up to 70 centimetres (28 in)) is taken into account.
It diet consists ants, termites and other insects.
- An aardvark's tongue can be up to 12 in (30.5 cm) long and is sticky to help extract termites from the earthen mounds.
