The Common warthog (Phacochoerus africanus) is a wild member of the pig family (Suidae) found in sub-Saharan Africa. It is the only pig species that has adapted to grazing and savanna habitats.
Common warthogs are found in sub-Saharan Africa. They live in grasslands, savanna, open bushlands, and woodlands. These animals prefer open areas and avoid rainforests, thickets, cool montane grasslands, and severe deserts.
A warthog has two pairs of tusks protruding from the mouth and curving upwards. The lower pair, which is far shorter than the upper pair, becomes razor-sharp by rubbing against the upper pair every time the mouth is opened and closed. The upper canine teeth can grow to 25.5 cm (10.0 in) long and have a wide elliptical cross-section, being about 4.5 cm (1.8 in) deep and 2.5 cm (0.98 in) wide. A tusk will curve 90° or more from the root, and will not lie flat on a table, as it curves somewhat backward as it grows. The tusks are not used for digging, but are used for combat with other hogs and in defense against predators - the lower set can inflict severe wounds. Common warthog ivory is taken from the constantly growing canine teeth. The tusks, particularly the upper set, work in much the same way as elephant tusks with all designs scaled down. Tusks are carved predominantly for the tourist trade in eastern and southern Africa. The head of the Common warthog is large, with a mane down the spine to the middle of the back. Sparse hair covers the body. Its color is usually black or brown. Tails are long and end with a tuft of hair. Common warthogs do not have subcutaneous fat and the coat is sparse, making them susceptible to extreme environmental temperatures.
