The blackbuck is the only living species of the genus Antilope. Its generic name stems from the Latin word antalopus, a horned animal. The species cervicapra is composed of the Latin words capra, she-goat and cervus, deer.
Males and females have distinctive coloration. Male blackbucks are dark brown, black, and white and have long, twisted horns, while females are fawn-coloured with no horns. Blackbucks closely resemble kobs.
Body length: 100–140 cm (3.3–4.6 ft)
Shoulder height: 64–84 cm (2.10–2.76 ft)
Tail length: 10–17 cm (3.9–6.7 in)
Weight: 25–40 kg (55–88 lb)
The horns of the blackbuck are ringed with one to four spiral turns, with rarely more than four turns; they can be as long as 79 cm (31 in). A trophy blackbuck is greater than 46 cm (18 in). In the male, the upper body is black (dark brown), and the belly and eye rings are white. The light-brown female is usually hornless.
Albinism in blackbuck is rare and caused by the lack of the pigment melanin. The animal looks fully white due to the lack of melanin in its skin. Wildlife experts say the biggest problem with these albinos is they are singled out by predators and hunted.
