The warthog is a wild animal native to the planet Earth. A warthog is an animal that is related to the domestic pig. Warthogs and male pigs both have snouts and both of these animals love to wallow in mud. Like a boar, they have tusks, so they can use them to dig a warthog burrow. The predators of the warthog are the Lion and the Hyena, even the Cheetah. In the science fiction movie After Earth the warthogs first appeared in the movie.
