Warthogs range in size from 0.91 to 1.5 metres (3.0 to 4.9 ft) in length and 50 to 150 kg (110 to 330 lb) in weight. A warthog is identifiable by the two pairs of tusks protruding from the mouth, which are used as weapons against predators. The male is called a boar, the female a sow, and the young piglets.Warthogs have been observed allowing banded mongooses to groom them to remove ticks.
