The hartebeest is a large African antelope with a long muzzle and horns in both sexes. It lives in herds on open grassy plains and runs quickly when in danger.
The hartebeest differs from other antelopes by its very long muzzle and unique horn shape. It is important for the savanna because it eats grass and serves as prey for lions, leopards, and hyenas.
