Interesting Facts About Aardvark

Aardvark – The aardvark (Orycteropus afer) is a remarkable and enigmatic mammal native to sub-Saharan Africa. With its unique appearance and fascinating adaptations, the aardvark holds a special place in both folklore and scientific study. Characterized by its robust body, elongated snout, and powerful claws, the aardvark is perfectly adapted for its specialized diet of ants and termites. Despite its somewhat bear-like appearance, the aardvark is not closely related to any other living mammal, representing a distinct evolutionary lineage. As a nocturnal creature, it spends its nights foraging for food and excavating burrows, while resting during the day in underground dens. While facing challenges such as habitat loss and human encroachment, the aardvark remains an iconic symbol of African wildlife, captivating the imagination of people around the world.

Interesting Facts

The Name Aardvark Means Earth Pig

For millennia, humans have shared their landscape with aardvarks, yet the creature acquired its modern moniker in the 17th century when Dutch settlers arrived in southern Africa. Observing its habit of burrowing into the earth, they coined the name “aardvark,” meaning “earth pig.” While indigenous tribes likely had their own names for this animal, they have faded from historical records. Occasionally known as the African ant bear or the cape anteater, “aardvark” holds a prominent position in English dictionaries and alphabetical lists of animals, symbolizing its unique place in the natural world.

Aadvarks Are the Sole Species of Their Mammalian Order

The approximately 15 existing species of aardvarks are members of the mammalian order Tubulidentata, classified within the genus Orycteropus, derived from the Greek for “burrowing foot.” Tubulidentatans emerged in Africa shortly after the extinction of dinosaurs, around 65 million years ago. Despite their early presence, they were not plentiful, as evidenced by the scarcity of fossil remains, although the prehistoric genus Amphiorycteropus is notable. The name Tubulidentata originates from the unique structure of these mammals’ teeth, consisting of bundles of tubes filled with a protein called vasodentin, in contrast to typical molars and incisors. Interestingly, aardvarks are born with conventional mammalian teeth at the front of their snouts, which are shed and not replaced shortly after birth.

Aadvarks Are the Size and Weight of Full-Grown Humans

Contrary to common perception, aardvarks are not the size of anteaters but rather substantial mammals, weighing between 130 to 180 pounds. This places them squarely within the weight range of average adult human males and females. Aardvarks are characterized by their stout legs, elongated snouts, large ears, small black eyes, and distinctly curved backs. Upon closer inspection, you’ll observe their four-toed front feet and five-toed rear feet, each bearing a flat, shovel-like nail resembling a hybrid of a hoof and a claw.

Aardvarks Live in Sub-Saharan Africa

Despite its peculiar appearance, the aardvark is remarkably adaptable, thriving across the vast expanse of sub-Saharan Africa. Found in diverse habitats including grasslands, bushlands, savannahs, and even some mountainous regions, it demonstrates remarkable resilience. The only environments where aardvarks are notably absent are swamps and lowlands, where the water table impedes burrowing. Interestingly, aardvarks are entirely absent from Madagascar, likely due to its geological separation from Africa around 135 million years ago. This suggests that aardvarks never had the opportunity to colonize the island from the eastern coast of Africa.

Aardvarks Eat Ants and Termites and Chew With Their Stomachs

A single aardvark can consume an astonishing 50,000 ants and termites in a single night, using its narrow, sticky, foot-long tongue to capture its prey. To supplement its insect-rich diet, the aardvark also feeds on the aardvark cucumber, a plant whose seeds are spread through aardvark dung. Due to the unique structure of their teeth, aardvarks swallow their food whole, relying on their muscular stomachs to “chew” the food into a digestible form. You’ll rarely find an aardvark near a typical African watering hole, as the concentration of predators makes it extremely perilous. Besides, the aardvark derives most of its necessary moisture from its insect-laden diet.

Aardvarks Have the Best Sense of Smell in the Animal Kingdom

While dogs are often celebrated for their keen sense of smell, the average aardvark surpasses them in olfactory prowess. Aardvarks boast long snouts equipped with approximately 10 turbinate bones, compared to the four or five found in canines. These hollow, seashell-shaped structures facilitate the passage of air through nasal passages. It’s not the bones themselves that enhance the aardvark’s sense of smell, but rather the epithelial tissues lining them, covering a significantly larger area. Consequently, aardvarks possess notably prominent olfactory lobes in their brains, enabling them to detect ants and grubs from considerable distances away.

Aardvarks Are Only Distantly Related to Anteaters

At first glance, aardvarks bear a striking resemblance to anteaters, leading to occasional references to them as Cape anteaters. While it’s true that these creatures share a distant common ancestor dating back around 50 million years, they are otherwise largely unrelated. Any resemblances between them can be attributed to convergent evolution, whereby animals in similar environments with similar diets evolve similar features. Interestingly, aardvarks and anteaters inhabit entirely different continents—anteaters are exclusive to the Americas, while aardvarks are confined to sub-Saharan Africa.
