The '''Aardvark''' (''Orycteropus afer'') ("Digging foot"), sometimes called "antbear"<ref name="eb">, "[http://search.eb.com/eb/article-9003204 aardvark]." [[Encyclopædia Britannica]]. 21 December 2006.</ref> is a medium-sized [[mammal]] native to [[Africa]]. The name comes from the [[Afrikaans]]/[[Dutch language|Dutch]] for "earth pig" (''aarde'' earth, ''varken'' pig), because early settlers from [[Europe]] thought it resembled a [[pig]]. However, the Aardvark is not closely related to pigs, being placed in its own [[order (biology)|order]].

==Description==
One of the most distinctive characteristic of the Tubulidentata is (as the name implies) their teeth. Instead of having a [[pulp (tooth)|pulp cavity]] in their tooth, they have a number of thin tubes of [[dentine]], each containing pulp held together by [[cementum]]. The teeth have no enamel coating and are worn away and regrow continuously. The Aardvark is born with conventional incisors and [[canine tooth|canines]] at the front of the jaw, which fall out and are not replaced. Adult Aardvarks only have molars at the back of the jaw. [[Gene]]tically speaking, the Aardvark is a living fossil, as its [[chromosome]]s are highly conserved, reflecting much of the early [[eutherian]] arrangement before the divergence of the major modern mammalian [[taxon|taxa]].<ref> [http://news.bbc.co.uk/2/hi/science/nature/2676377.stm BBC News - Science/Nature - Great Uncle Aardvark?]</ref>

The Aardvark is vaguely pig-like. 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 — but 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, protruding tongue and elaborate structures supporting a keen [[olfaction|sense of smell]].

An aardvark's weight is typically between 40 and 65 kg. An aardvark's length is usually between 1 and 1.3 meters, and can reach lengths of 2.2 meters<ref name="eb"/> when its tail (which can be up to 70 centimeters)<ref name="eb"/> is taken into account. The aardvark is pale yellowish gray in color,and often stained reddish-brown by soil. The aardvark's coat is thin and the animal's primary protection is its tough skin. The aardvark has been known to sleep in a recently excavated ant nest, which also serves as protection. The number of aardvarks has nearly doubled since 2002, scientists say.

==Behavior==
The Aardvark is [[nocturnal]] and is a solitary creature that feeds almost exclusively on [[ant]]s and [[termite]]s (formicivore); the only [[fruit]] eaten by aardvarks is the [[aardvark cucumber]]. An aardvark emerges from its burrow in the late afternoon or shortly after sunset, and forages over a considerable home range encompassing 10 to 30 kilometers,<ref name="eb"/> swinging its long nose from side to side to pick up the scent of food. When a concentration of [[ants]] or [[termites]] is detected, the Aardvark digs into it with its powerful front legs, keeping its long ears upright to listen for predators, and takes up an astonishing number of [[insects]] with its long, sticky tongue &mdash; as many as 50,000 in one night have been recorded. It is an exceptionally fast digger, but otherwise moves fairly slowly. Its claws enable it to dig through the extremely hard crust of a termite mound quickly, avoiding the dust by sealing the nostrils. When successful, the aardvark's long (as long as 30 centimeters)<ref name="eb"/> tongue licks up the insects; the termites's stinging attacks are rendered futile by the tough skin. Its keen hearing warns it of predators: lions, leopards, hyenas, and pythons.

Aside from digging out ants and termites, the aardvark also excavates burrows in which to live: temporary sites are scattered around the home range as refuges, and a main burrow is used for breeding. Main burrows can be deep and extensive, have several entrances and can be as long as 13 meters. The Aardvark changes the layout of its home burrow regularly, and from time to time moves on and makes a new one; the old burrows are then inhabited by smaller animals like the [[African Wild Dog]].<ref name="eb"/> Only mothers and young share burrows. If attacked in the tunnel, it will seal the tunnel off behind itself or turn around and attack with its claws.

Aardvarks only pair during the breeding season; after a [[gestation]] period of 7 months, a single cub weighing around 2 kg is born, and is able to leave the burrow to accompany its mother after only two weeks, and is eating termites at 14 weeks and is weaned by 16 weeks.<ref name="eb"/> At six months of age it is able to dig its own burrows, but it will often remain with the mother until the next [[mating season]], and is sexually capable by the season after that.

Aardvarks can live to be over 24 years old in [[captivity]].<ref name="eb"/>

The aardvark's main predators are lions, leopards, hunting dogs and pythons. Aardvarks can dig fast or run in zigzag fashion to elude enemies, but if all else fails, they will strike with their claws, tail and shoulders, sometimes flipping onto their backs to lash with all fours. Their thick skin also protects them to some extent.

==Habitat==
Aardvarks live in [[Subsaharan Africa]], where there is suitable habitat for them to live, such as [[savanna]]s, [[grassland]]s, [[woodland]]s and [[bushland]], and available food (i.e., ants and termites).

==Mythology==
In African folklore the aardvark is much admired because of its diligent quest for food and its fearless response to soldier ants. [[Hausa]] magicians make a charm from the heart, skin, forehead, and nails of the aardvark, which they then proceed to pound together with the root of a certain tree. Wrapped in a piece of skin and worn on the chest the charm is said to give the owner the ability to pass through walls or roofs at night. The charm is said to be used by burglars and those seeking to visit young girls without their parent's permission.{{Fact|date=November 2007}}
