An antelope is any of several cloven hoofed ruminates, members of a large family, closely resembling the Deer in general appearance, but essentially different in nature from the latter animals. They are included with the Sheep and Oxen in the family of the Cavicornia or 'Hollow-horned' Ruminants. Their horns, unlike those of the Deer, are not deciduous, but are permanent; are never branched, but are often twisted spirally, and may be borne by both sexes. They are found in greatest number and variety in Africa. Well-known species are the chamois (European), the gazelle, the addax, the eland, the kudu, the gnu, the springbok, the sasin or Indian antelope, and the prongbuck of America. Research Antelope
