There are actually two different species of Warthog.
The Common Warthog (P. africanus) and the Desert
Warthog (P. aethiopicus). Warthogs are a member of
the pig family, and are identifiable in their family by the
two tusks coming from their mouth. They use the tusks for protection
from predators. They also have four wart-like protusions on
the top of their head, which is also used for defense when male
Warthogs are fighting.
