The wildebeest (plural, wildebeest or wildebeests), also called the gnu ( or /ˈnjuː/), is an antelope of the genus Connochaetes. It is a hooved (ungulate) mammal. It looks like a mixture of features between a cow and a horse.
Connochaetes includes two species, both native to Africa: the Black Wildebeest, or white-tailed gnu (C. gnou), and the Blue Wildebeest, or brindled gnu (C. taurinus). Gnus belong to the family Bovidae, which includes antelopes, cattle, goats, and other even-toed horned ungulates.
Wildebeest grow to 3 ft 9 in-4 ft 7 in (1.15-1.4 metres) at the shoulder and weigh 330-550 pounds (150-250 kilograms). They inhabit the plains and open woodlands of Africa, especially the Serengeti. Wildebeest can live more than 20 years.
