Warthog in Swahili: ngiri (Phacochoerus africanus)
Shoulder height: 60 – 70 cm; weight: 100 kg. This widespread and often conspicuously abaundant resident of the African savanna mid-grey in colour with tin covering of hairs, wart-like bumps on its face, and rather large upward-curvung tusks. Africa’s only diurnal swine, the worthog is off briskly with its tail raised stiffly (a diagnostic trait) and a determinedly nonchalant air. Two other swine species are present but seldom seen in Tanzania. The bulkier, hairier and browner bushpig (potamochoerus larvatus) is as widespread as the worthog, but it is infrequently seen due to its nocturnal habits and preference for dense vegetaion. Larger still, weighing up tp 250 kg, the giant forest hog (Hylochoerus meinertzhageni) is a primarily West African rainforest species known from a few highland forests in northern Tanzania, but the chance of a sighting is practically non-existent.
