Warthogs (Phacochoerus africanus) are common in savanna habitats in southern Africa. Their name refers to their conspicuous facial “warts”, two on each side of the face in males and only one pair in females. Male Warthogs are much larger than females, and may grow to over 100 kilograms (220 pounds) with tusks up to 60 centimetres (24 inches) long. Warthogs have short, thin legs, short necks and protuberant tusks in their upper and lower jaws. The tusks in the upper jaw are curled, while the lower jaw tusks are less obvious, with their edges and tips kept sharp by rubbing against the upper tusks. The lower tusks are more important in defence, and can kill or maim would-be predators such as Leopards. This massive male Warthog was grazing on grass on the road verge in the Hoedspruit Wildlife Estate. He was wary at first, but relaxed after a while and dropped to his knees to get his mouth closer to the grass. He had the largest tusks I had ever seen, and was not unduly bothered by me as I stood a few metres away with my video camera.
