Warthogs famously modify and use existing tunnel systems, most commonly those originally excavated by which animal?
Answer
Aardvarks
Warthogs possess a distinct behavioral quirk regarding their shelter; they are not tunnel engineers themselves and do not dig extensive burrows from scratch. Instead, they are opportunistic residents that locate and repurpose existing underground tunnels. The text highlights that the most famous source of these modified retreats is the extensive burrowing work performed by aardvarks. Warthogs will enter these tunnels to sleep at night or to escape midday heat or predatory threats, adapting them slightly to fit their needs.
