The aardwolf is without doubt one of the most specialised carnivores on the African continent, but it tends to stay within the shadow of its canine cousins, hyenas. Its curious palate for termites apart, aardwolves have amusing evolutionary oddities and a scandalous social life, the place they’ll typically cuckold with neighbours regardless of their monogamous pairings.
What’s an aardwolf?
When straight translated from Afrikaans, aardwolf means ‘earth wolf’ and confer with their underground dens and canine-like look.
The species happens solely in Africa with two distinct populations: one within the east of the continent from Egypt south to central Tanzania, and one other starting from Angola and Mozambique into Southern Africa.

Once they attain one 12 months outdated, each female and male aardwolves go away the den to determine their very own territory.
Conservation standing
They’re listed as Least Concern on the IUCN purple checklist of threatened species each globally and regionally in South Africa. The final evaluation of aardwolves in 2016 discovered them to have thriving populations in lots of nationwide parks and reserves, together with the Kgalagadi Transfrontier Park, Kruger Nationwide Park and Pilansberg Nationwide Park.
Though habitat loss might be problematic, aardwolves have proven nice resilience and the power to adapt to totally different areas. Many cattle farms with a prevalence of termite mounds report common sightings of aardwolves.
The Environmental Wildlife Belief states that there are presently no main threats to aardwolves however they could be susceptible to future environmental adjustments as a specialised predator depending on grassland environments.
Within the wild, predators akin to leopards, lions and different hyenas are identified to kill each aardwolves and their cubs.
