Aardvark

The Aardvark, Orycteropus afer, sometimes called the “˜antbear’, is a medium-sized mammal native to Africa. It lives south of the Sahara desert where there is suitable habitat for them to live. It prefers savannas, grasslands, woodlands and bush. They are not found in deserts but are found in areas where there is a good supply of ants and termites.

The most distinctive characteristic of the Aardvark is their teeth. Instead of having a pulp cavity, they have a number of thin tubes of dentine, each containing pulp and held together by a cement-like substance. The teeth have no enamel coating and are worn away and regrow continuously. The Aardvark is born with conventional incisors and canines at the front of the jaw, but these fall out and are not replaced. Adult Aardvarks have only molars at the back of the jaw.

The body of the aardvark is sparsely scattered with coarse hairs. The body is stout with an arched back and the limbs are of moderate length. The front feet have only 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 house the nostrils. The mouth is small and tubular, typical of species that feed on termites. The aardvark has a long, thin, able-protruding tongue and elaborate structures supporting a keen sense of smell.

An aardvark’s weight is typically between 40 and 65 kg; length is usually between 1 and 1.3 meters, and can reach lengths of 2.2 meters when its heavy tail (which can be up to 70 centimeters) is taken into account. The aardvark is a pale yellowish gray in color, often stained reddish-brown by soil. The coat is thin and the animal’s primary protection is its tough skin. 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.

The Aardvark is nocturnal and is a solitary creature that feeds almost exclusively on ants and termites. 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 6 to 18 miles, 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. As many as 50,000 ants and termites in one night have been recorded.

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 42 feet. The Aardvark changes the layout of its home burrow regularly, and from time to time moves on and makes a new one. 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 certain breeding seasons. After a gestation period of 7 months, a single cub weighing around 4 lbs 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. 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.
