T<\/span>he warthog (Phacochoerus africanus) is a nearly hairless pig with gray to brown skin, long legs, a straight back, large, flattened head, a dark mane of long, coarse hair, and two pairs of curved tusks. The face of male warthogs has three pairs of large, wart-like masses of thickened skin and connective tissue called callosities that protect the eyes and snout during fights with other males. The more peaceable female has smaller tusks than males and smaller callosities.<\/p>\n<\/div>
