The warthog is essentially a member of the pig family, but with some unusual differences. These two were in Arusha, in Tanzania, Africa. There are four wart like growths on their head, both as a fat reserve, and as part of a defense mechanism when fighting. They also sport two sets of ugly looking tusks, used as digging tools when feeding. Although they are prey to many of the meat eating beasts, those tusks can do great damage. Lions can often be so gored as to bleed to death in a fight. Also, because their head and neck cannot reach the ground while standing, they must kneel to reach down far enough to dig. The Serengeti Masai joke that warthogs are really praying for a prettier face when on their knees.
