A warthog is a wild pig that lives in the grasslands and savannas of Africa. Despite its name, warthogs aren't covered in warts. Those bumps on their face are actually thick pads of skin and fat that protect their head during fights with other warthogs or when defending themselves from predators like lions and leopards.

Warthogs have a distinctive look: they're gray and mostly hairless, with a bristly mane running down their spine, and most notably, they have four large tusks curving up from their mouth. Males use these tusks when battling each other. When a warthog runs, it holds its thin tail straight up like an antenna, which helps members of the family group keep track of each other in tall grass.

Unlike their cartoon portrayals, real warthogs are quite speedy and can run up to 30 miles per hour. They're also surprisingly clever: they back into underground burrows (often abandoned aardvark holes) so they can face any danger head-first with their tusks ready. They kneel on their front legs to eat grass and roots, almost like they're bowing down for dinner.
