They belong to the family Bovidae, which includes antelopes, cattle, goats, sheep, and other even-toed horned ungulates. "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"). Fossil records suggest these two species diverged about one million years ago, resulting in a northern and a southern species. The blue wildebeest remained in its original range and changed very little from the ancestral species, while the black wildebeest changed more in order to adapt to
Blue wildebeest appear long, stiff, thick, and jet black, the same colour as the tail and face. While the manes of the western and eastern white-bearded wildebeest are lank, those of the Nyassaland wildebeest and common wildebeest stick up. Scent glands, which secrete a clear oil, are present in the fore feet and are larger in males than females. In terms of skull length, the smallest subspecies of the blue wildebeest is the western white-bearded wildebeest. It is also the darkest subspecies; the eastern white-bearded wildebeest is the lightest race. Both subspecies possess a creamy white beard, whereas the beard is black
