Their name comes from their ‘warts’ or protrusions on the sides of their face, these protrusions are a combination of bone and cartilage.  It protects their face when they fight.

They sleep underground at night in burrows that they steal from other animals such as aardvark. They don’t dig their own.

They like to roll in the mud to protect their skin from the sun and from parasites.
Warthogs have litters of two to four piglets however, their mortality rate is quite high due to predators.

Two or three female warthogs form small sounders with their young as they look after the piglets.

Female warthogs let their babies go into their burrows first, then they back into the burrow so that if anything comes into the burrow as a threat she can run out and protect them.

They have tusks like an elephant, on their upper and lower jaws that they use to fight and defend themselves against predators. If the ground is hard, they use their snouts and tusks to lift the soil. They go down onto their wrists when they eat.

Surprisingly, they can live for up to 17 years of age.
