The Oribi is the largest of the dwarf antelope, a group that includes royal antelope, dik-diks and klipspringers. It is the only antelope that feeds mainly on grass. The oribi lives in places where the grass is short so it can look out for danger. It is red-brown with white underparts and a black tail. It also has a black spot beneath each ear. These spots have glands that release its scent into the air.
