Zoo Aardvark Welfare | Animal Welfare Hub

Aardvarks are nocturnal insectivores with specialist welfare needs that make them challenging but fascinating zoo residents.

Key Facts

Aardvarks are the sole member of the order Tubulidentata — an evolutionary lineage with no close living relatives
They excavate extensive burrow systems using powerful claws, making digging substrate a fundamental welfare requirement
Aardvarks are exclusively insectivorous, feeding on ants and termites in the wild — captive diets require careful formulation
They are strictly nocturnal, making them poor subjects for daytime zoo viewing unless nocturnal exhibits are provided
Their large, mobile ears and excellent olfactory sense are primary sensory organs — olfactory enrichment is important
Captive aardvarks can become overweight on concentrated diets that lack the natural exercise required to obtain food
They are solitary in the wild — social housing is not appropriate and can cause chronic stress

Welfare Considerations

Aardvark welfare in captivity requires commitment to their unusual biological needs. Digging is not optional enrichment for aardvarks — it is a fundamental behavioral expression of a species whose entire anatomy evolved around excavation. Exhibits without deep, appropriate digging substrate deny this core behavioral system. Nocturnal management that forces aardvarks into daytime activity conflicts with their biological clock. Diet formulation that fails to provide the physical effort associated with natural foraging contributes to obesity and behavioral boredom. These are demanding welfare requirements that commit a facility to significant ongoing investment, but they are the minimum needed to house aardvarks in genuinely welfare-positive conditions.
