The aardvark differs from the anteater, sloth, armadillo, and all other mammals. It is the only member of the order Tubulidentata (tubule toothed), so named because of a permanent set of twenty teeth that have tubular pulp cavities extending through them from top to bottom. The teeth are rootless. Dutch farmers who first encountered the animal in South Africa called it an aardvark, which means "earth pig" in the Dutch language. It is also sometimes called the African ant bear. It looks like a giant, hump-backed rat with the head of an anteater, the nose of a pig, and the ears of a rabbit. It is unrelated, however, to any other mammal.
Physical Characteristics of Aardvarks
The typical aardvark is about 7.5 feet long and weighs between 110 and 150 pounds, though the largest may weigh up to 180 pounds. It has a long, ratlike tail and a foot-long, sticky tongue that usually hangs out of its mouth. The tongue is curled like a coiled spring and is unleashed quickly as the aardvark sucks in its meal of ants or termites. It is perfectly suited for inserting into nests, and the termites adhere to the sticky surface. Adult aardvark have one- to two-inch-long whitish hairs growing fromeach nostril, and twenty teeth along the sides of the mouth, that are always growing. The nose hairs protect aardvark from dust and dirt while they are digging.Young aardvark have front teeth that fall out as the animals reach maturity. Aardvark teeth are unique in the animal kingdom, as they are rootless, lack dentine, and have hollow tubes running through them. Thick brown hair covers aardvark' pinkishgray skin. The hair serves to protect members of the species from insect bites. They have short, stocky legs and small feet with long, straight, very strong, blunt claws. Their front feet have four toes, while rear feet have five toes. The rear toes are webbed at the bottom. An aardvark looks like no other animal on earth.
