Phacochoerus is a genus of wild pigs in the Suidae family that are known as warthogs. It is the sole genus of subfamily Phacochoerinae. They are found in open and semi-open habitats, even in quite arid regions, in sub-Saharan Africa. The two species were formerly considered conspecific under the scientific name Phacochoerus aethiopicus, but today this is limited to the Desert Warthog, while the best-known and most widespread species, the Common Warthog (or simply Warthog) is Phacochoerus africanus.^[1]

Phacochoerus africanus

Although covered in bristly hairs, their body and head appear largely naked from a distance, with only the crest along the back, and the tufts on the cheeks and tail being obviously haired. The English name refers to their facial wattles, which are particularly distinct in males. They also have very distinct tusks, which reach a length of 25.5 to 63.5 centimetres (10.0 to 25.0 in) in the males, but are always smaller in the females.^[2] They are largely herbivorous, but occasionally also eat small animal food.^[3] While both species remain fairly common and widespread, and therefore are considered to be of Least Concern by the IUCN, the nominate subspecies of the Desert Warthog, commonly known as the Cape Warthog, became extinct around 1865.^[4]
