The duikers are a group of small, straight-horned antelopes of forest and thick brush country. Gazelle is the name for a number of small, delicate antelopes with spreading horns, inhabiting deserts and grassy plains. The largest of these is the pale brown impala , the kind of antelope best known from motion pictures. The blackbuck, found in India, was the first antelope to be described by zoologists, and has the generic name Antilope. The delicate pygmy antelopes include the royal antelope, beira, klipspringer, oribi, grysbok, steinbok, dik-dik, and suni.
Males have tiny, straight horns.
The nilgai and the four-horned antelope are found in SE Asia. More closely related to the goats than to any of the above-named animals, but often called antelopes, are the saiga of central Asia and the chiru of Tibet. Antelopes are classified in the phylum Chordata , subphylum Vertebrata, class Mammalia, order Artiodactyla, family Bovidae. Licensed from Columbia University Press.
