As their name suggests, warthogs have facial warts, three pairs to be exact: the suborbital warts (the largest, up to 6 inches in males), the preorbital warts (not as developed in females), and the submaxillary warts (with white bristles). In addition, warthogs also have tusks, 10 to 25 inches long for males and 6 to 10 inches long for females.
Warthogs can be found in one of three different social structures: (1) solitary adult males, (2) bachelor groups of adolescent males, or (3) groups, called sounders, of 4 to 16 females and their young—females will temporary become solitary prior to giving birth.

Territorial behavior is not prominent in this species, with home ranges overlapping those of other individuals. In fact, resting, feeding, drinking, and wallowing sites are often shared with others. When frightened, warthogs run with their tail upright to alarm conspecifics.
