Warthog

The Warthog or Common Warthog (Phacochoerus africanus, "African Lens-Pig") is a wild member of the pig family that lives in Africa.
The common name comes from the four large wart-like protrusions found on the head of the warthog, which serve the purpose of defense when males fight. They are the only widely recognised species in their genus, though some authors divide them into two species. On that classification, P. africanus is the Common (or Northern) Warthog and P. aethiopicus is the Desert Warthog, also known as the Cape or Somali Warthog.
