A warthog is a wild pig of the genus Phacochoerus in the family Suidae, native to Africa. It is known for its large head, sparse hair, facial swellings that resemble warts, and prominent tusks. Warthogs live in open and lightly forested habitats and are commonly associated with sub-Saharan Africa.

Taxonomy and classification

Warthogs are members of the pig family Suidae. Some references treat warthogs as a genus with two species, while others focus on the common warthog and use different species-level classifications.

Physical characteristics

Warthogs are sparsely haired, brownish or blackish animals with coarse manes, long tails, and large tusks. The facial swellings that give them their name are most prominent in males. They have two pairs of tusks, with the lower tusks used as defensive weapons. Typical shoulder height is about 76 cm.

Habitat and distribution

Warthogs are found in Africa, especially in open and semi-open habitats such as grassland, savanna, and lightly forested areas. They are adapted to arid and semi-arid regions as well as more open woodland. Their range includes sub-Saharan Africa.

Behaviour and diet

Warthogs are social animals that often live in groups. They feed mainly on grass and other vegetation, though some sources describe them as omnivores. They often shelter in enlarged aardvark burrows and back in to defend themselves from predators.
