Why do Warthogs Roll in the mud

Did you know!!!! Warthogs like to roll in the mud to protect their skin from the sun and from parasites?They sleep underground at night in burrows that they steal from other animals such as aardvark. They don’t dig their own.Warthogs mainly eat grass or will dig for roots and bulbs when it’s dry. If they have the opportunity, they will scavenge on meat as they are omnivorous.
