Aardvark facts worth knowing: an aardvark can eat over 50,000 insects a night, dig a burrow 6 metres deep in under 15 minutes, and belongs to an order with no other living members. It isn't a pig, and it isn't related to anteaters despite the resemblance.
It Isn't a Pig, and It Isn't Related to Anteaters
I got this wrong myself the first time I read about aardvarks, back before I ever wrote a word about Africa's wildlife for a living. The name "aardvark" is Afrikaans for "earth pig," and the long snout does the rest of the misleading work. But an aardvark isn't a pig, and it isn't a relative of the anteaters it resembles either.
It's the only living species in the order Tubulidentata. Its closest relatives, according to molecular studies grouped under the Afrotheria classification, are elephants, manatees, and hyraxes, animals it looks nothing like. That single-species order is rare among mammals. Most orders hold dozens of species. Tubulidentata holds exactly one.
On a research trip near Tswalu in South Africa's Kalahari region, a tracker named Elias showed me a set of four-toed front prints pressed into red sand and asked what animal made them. I guessed warthog. I was wrong by an entire mammalian order, and Elias still brings it up.
The 30-Centimetre Tongue Behind the Diet
An adult aardvark's tongue runs about 30 centimetres long and stays coated in a sticky saliva that traps insects on contact. That single tool explains almost everything else about how the animal lives. It doesn't chew its food. It swallows ants and termites whole, and a muscular stomach called a pyloric region grinds them down instead.
Researchers tracking aardvark foraging in Karoo National Park have recorded single animals visiting over 200 separate termite mounds and ant nests in one night, spending as little as a few minutes at each before moving on. A night's total can run past 50,000 individual insects, based on stomach content studies from the same region.
That diet is also why aardvarks avoid areas that have been heavily sprayed with pesticides. Fewer termite mounds means fewer stops on the circuit, and an animal that depends on quantity over variety feels that shortage fast.
A Burrow Six Metres Deep, Dug Before Sunrise
Aardvarks are fast, serious diggers. Field observations describe an adult carving out a new burrow entrance and disappearing underground in under 15 minutes when startled, using front claws built more like small shovels than fingers.
A single home burrow can run 6 metres deep and stretch further than that in tunnel length, with side chambers used for sleeping and raising young. Some individuals keep several burrows across their home range and rotate between them, the same way a person might keep a spare set of keys at a second address.
Here's the thing that surprised me most on that Kalahari trip: none of it goes to waste once the aardvark moves on. Warthogs, porcupines, hyenas, and even ground squirrels reuse abandoned aardvark burrows for shelter, cover, and raising their own young. Guides at Tswalu told me they've found three different species denning in the same disused burrow across a single dry season. If you want more on that, our piece on how aardvarks build and abandon their burrows goes into the digging mechanics in more depth.
Ears Built for Hearing, Not Just for Looks
Those tall, tube-shaped ears aren't just a visual trademark. They can rotate independently and pick up the low sound of insects moving inside a mound, or a predator approaching from behind while the aardvark's head is down in a hole.
Aardvarks fold their ears flat against the skull while actively digging, which keeps sand out and still leaves enough exposed to register a warning. Between hearing and a strong sense of smell, sight does comparatively little work for this animal. You can read more about the trade-offs in our guide to aardvark anatomy and adaptations.
Where Aardvark Facts Get Tested in the Field
Aardvarks range across most of sub-Saharan Africa, from Senegal in the west to South Africa in the south, wherever soil is soft enough to dig and termite or ant colonies are dense enough to support nightly foraging.
- Savanna and grassland, the most common habitat type across their range
- Semi-arid scrub, including parts of the Kalahari and Karoo
- Open woodland with sandy or loamy soil
According to the IUCN Red List, the species is absent from dense rainforest and true desert, both places where digging conditions or insect density fall too low to support them. Our habitat and range guide maps that distribution country by country.
What "Least Concern" Actually Means Here
The aardvark currently holds a Least Concern status on the IUCN Red List, which reflects a wide range and no sign of steep, continent-wide decline. That's not the same as saying every local population is thriving.
Drought has been linked to localised die-offs in parts of southern Africa, since dry soil pushes termites deeper and forces aardvarks to burn more energy for less food. Researchers I've corresponded with treat that as one of the more likely near-term pressures on the species, more than direct hunting in most regions.
Frequently Asked Questions
How many aardvark facts are actually verified by researchers?
Most core aardvark facts, like diet, burrow depth, and gestation length, come from field studies tracking radio-collared animals in places like the Kalahari and Serengeti. Behaviour claims without a study behind them get flagged as unverified on this site rather than repeated as settled fact.
Why do people confuse aardvarks with anteaters or pigs?
The snout does it. "Aardvark" is Afrikaans for earth pig, and the long nose looks anteater-like at a glance. But an aardvark isn't related to either animal. It's the only living species in the order Tubulidentata, closer on the family tree to elephants and manatees than to any pig.
Can you see an aardvark on a normal safari?
Rarely, and that's expected, not a failure of planning. Aardvarks are strictly nocturnal and spend daylight underground, so most sightings happen on dedicated night drives with a spotlight, and even then guides often go a full week without one.
Are aardvarks endangered?
The IUCN currently lists the aardvark as Least Concern, meaning the overall population is considered stable across its range. That status can still hide local pressure from habitat loss and drought, which is why range data keeps getting updated.
The Bottom Line
The most useful aardvark facts aren't the strange trivia, they're the ones that explain behaviour: a 30cm tongue built for volume feeding, a burrow system dug in minutes and reused for years by other species, and ears tuned for a world experienced mostly after dark. None of that makes the aardvark a pig, and none of it makes an encounter with one common.
If you're planning a night drive specifically to see one, ask your guide about recent burrow activity in the area rather than hoping for luck alone.
