The wildebeest is also called the GNU. A wildebeest is an african animal that looks like a cow-like beast and sounds like a science fiction creature. Gnus eat grass and plants and get eaten by Lions, Leopards, wild dogs, and a Cheetah or Hyena packs. Gnus migrate all across east africa from the seregenti to the masai mara. In the movie, After Earth, the wildebeests evolved the horns of a Rhino, the hair of a Yak, and the hooves of a huge Rhinoceros. The gnus were canceled and replaced as Bison of the north american prairies of the united states' bison territories.
