Common warthog

Description

The common warthog is black or brown in color. Its body is virtually hairless except for a mane of long, stiff hairs on the neck and shoulders. The face is flat and has two pairs of warts; both sexes have well developed tusks that they use for self-defense and digging. With a large head, the warthog's eyes are positioned high on its skull so that it can watch out for lions and leopards, its chief predators. 

Ethology

They are daylight animals that live in family groups, normally comprising females and their young. The males become solitary after the age of two.  The female's gestation period is around 172 days. It may have between 1 and 7 young. It utilizes burrows dug by other animals, where it seeks protection from predators and extreme temperatures and where it gives birth to its young. It also uses them to rest. 

Interesting facts

Its main threats are the degradation of the habitat and the competition with livestock for water and food. It is hunted for sport and for its flesh, hide, and tusks, and is also used as bait for hunting large carnivores.
