   Either one of two species of large, savage African wild hogs
   of the genus {Phacoch[oe]rus}. These animals have a pair of

   both pairs curve upward. The body is scantily covered with
   bristles, but there is long dorsal mane. The South African
   species ({Phacoch[oe]rus [AE]thiopicus}) is the best known.
