Largest wild pig

The largest wild pig is the giant forest hog (Hylochoerus meinertzhageni) which lives across central Africa. It has a head–body length of 1.3–2.1 m (51–83 in), a tail length of 30–45 cm (12–17.75 in), a shoulder height of 85–105 cm (33.5–41.25 in) and a weight of 130–275 kg (287–606 lb)), yet remained undescribed by science until 1904.

Extremely fierce when excited, giant forest hogs have been seen driving solitary spotted hyenas off buffalo kills, and will attack humans if they are shot at. Competitions among males are violent and may extend for half and hour. During these contests, males rush directly at each other from 20–30m (64–96ft) apart, crashing their foreheads together with a loud smack in a manner reminiscent of wild sheep. The victor urinates, grinds his teeth, and bites at the loser, who in turn flees the area with his tail raised. Despite their reinforced skulls, deaths among males due to fractures and breaks are not uncommon. The forest hog is quite vocal, producing grunts and barks to communicate over both short and long distances.
