Phacochoerus aethiopicus Shoulder height 60–70cm. Weight up to 100kg.
This widespread and often conspicuously abundant resident of the African savannah is grey in colour with a thin covering of hairs, wart-like bumps on its face, and rather large upward curving tusks. Africa's only diurnal swine, the warthog is often seen in family groups, trotting around with its tail raised stiffly (a diagnostic trait) and a determinedly nonchalant air. They occur in most areas of Zambia, except in the extreme northwest, and are very common in most of the national parks. They don't usually fare well near settlements, as they are very susceptible to subsistence hunting/poaching. Wherever they occur, you'll often see them grazing beside the road, on bended knee, with their tails held high in the air as soon as they trot away.

Similar species: Bulkier, hairier and browner, the bushpig (Potomochoerus larvatus) is known to occur throughout Zambia, and even in the vicinity of cultivated land where it can do considerable damage to crops. However, it is very rarely seen due to its nocturnal habits and preference for dense vegetation.
