Warthogs use their tusks both for fighting off unwanted predators and other competing male warthogs, and the warthogs also use these tusks for digging in the dirt for grubs and insects. Warthogs have a diet that consists mainly of grass, fruit, berries, roots and insects but warthogs are also known to occasionally eat small mammals, birds and reptiles. The diet of the warthog however, depends on the season and what is growing and therefore available for the warthog to eat.
