Warthogs are members of the same family as domestic pigs, but present a much different appearance. These sturdy hogs are not among the world’s most aesthetically pleasing animals—their large, flat heads are covered with “warts,” which are actually protective bumps. Warthogs also sport four sharp tusks. They are mostly bald, but they do have some sparse hair and a thicker mane on their backs.
Though warthogs appear ferocious, they are basically grazers. They eat grasses and plants, and also use their snouts to dig or “root” for roots or bulbs. When startled or threatened, warthogs can be surprisingly fast, running at speeds of up to 30 miles an hour.
