The Warthog ("African Lens-Pig") is a wild member of the pig family that lives in Africa. The common name comes from the four large wart-like tusks found on the head of the warthog, which serve the purpose of defense when males fight.

Warthogs range in size from 0.9 to 1.5 metres (2.9-4.9 feet) in length and 50 to 150 kg (110-330 pounds) in weight. A warthog is identifiable by the two pairs of tusks protruding from the mouth, which are used as weapons against predators. The upper canine teeth can grow to 9 inches (23 cm), and are of a squashed circle shape in cross section, almost rectangular, being about 1 in (4.5 cm) deep and 1 in (2.5 cm) wide. The tusk will curve 90 degrees or more from the root, and the tusk will not lie flat on a table, as it curves somewhat backwards as it grows. The tusks are used for digging, for combat with other hogs and in defence against predators – the lower set can inflict severe wounds.
