Its face is long with fleshy warts and protruding tusks. Warthogs travel in groups called sounders consisting of 1 or 2 sows and young offspring. Males usually travel alone. Boars have more prominent warts than sows. They are primarily used to protect the face during fights.
Warthogs use burrows for shelter and when entering, the hogs back in.
This enables them to defend themselves. In the mornings, warthogs burst out of their burrows at top speed to get a running start on any predators that may be lurking nearby. Although they look fierce, warthogs would rather run than fight. But they can be fierce opponents if forced. Ecology and Conservation Warthogs allow birds, such as the yellow hornbills, to eat parasites that live on their bodies.
