Both species of wildebeest are even-toed, horned, greyish-brown ungulates resembling cattle. Males are larger than females and both have heavy forequarters compared to their hindquarters. They have broad muzzles, Roman noses, and shaggy manes and tails. The most striking morphological differences between the black and blue wildebeest are the orientation and curvature of their horns and the color of their coats. The blue wildebeest is the bigger of the two species. In males, blue wildebeest stand 150 cm tall at the shoulder and weigh around 250 kg, while the black wildebeest stands 111 to 120 cm tall and weighs about 180 kg. In females, blue wildebeest have a shoulder height of 135 cm and weigh 180 kg while black wildebeest females stand 108 cm at the shoulder and weigh 155 kg. The horns of blue wildebeest protrude to the side, then curve downwards before curving up back towards the skull, while the horns of the black wildebeest curve forward then downward before curving upwards at the tips. Blue wildebeest tend to be a dark grey color with stripes, but may have a bluish sheen. The black wildebeest has brown-coloured hair, with a mane that ranges in color from cream to black, and a cream-coloured tail. The blue wildebeest lives in a wide variety of habitats, including woodlands and grasslands, while the black wildebeest tends to reside exclusively in open grassland areas. In some areas, the blue wildebeest migrates over long distances in the winter, whereas the black wildebeest does not. The milk of the female black wildebeest contains a higher protein, lower fat, and lower lactose content than the milk of the blue wildebeest. Wildebeest can live more than 40 years, though their average lifespan is around 20 years.

The black wildebeest or white-tailed gnu ("Connochaetes gnou") is one of the two closely related wildebeest species. It is a member of the genus "Connochaetes" and family Bovidae. It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. The black wildebeest is typically in head-and-body length, and the typical weight is . Males stand about at the shoulder, while the height of the females is . The black wildebeest is characterised by its white, long, horse-like tail. It also has a dark brown to black coat and long, dark-coloured hair between its forelegs and under its belly.

Black wildebeest are sexually dimorphic, with females being smaller in size and more slender than males. The head-and-body length is typically between . Males reach about at the shoulder, while females reach . Males typically weigh and females . A distinguishing feature in both sexes is the tail, which is long and similar to that of a horse. Its bright-white colour gives this animal the vernacular name of "white-tailed gnu", and also distinguishes it from the blue wildebeest, which has a black tail. The length of the tail ranges from .

Black wildebeest are predominantly grazers, preferring short grasses, but also feeding on other herbs and shrubs, especially when grass is scarce. Shrubs can comprise as much as 37% of the diet, but grasses normally form more than 90%. Water is essential, though they can exist without drinking water every day. The herds graze either in line or in loose groups, usually walking in single file when moving about. They are often accompanied by cattle egrets, which pick out and consume the insects hidden in their coats or disturbed by their movements.

The blue wildebeest exhibits sexual dimorphism, with males being larger and darker than females. The blue wildebeest is typically in head-and-body length. The average height of the species is . While males weigh up to , females seldom exceed . A characteristic feature is the long, black tail, which is around in length. All features and markings of this species are bilaterally symmetrical for both sexes. The average life span is 20 years in the wild, and 21 years in captivity. The oldest known captive individual lived for 24.3 years.

Though they are not present in their natural habitat in such large numbers today, black wildebeest were at one time the main herbivores in the ecosystem and a main prey item for large predators such as the lion. Now, they are economically important for human beings, as they are a major tourist attraction, as well as providing animal products such as leather and meat. The hide makes good quality leather and the flesh is coarse, dry and rather hard. Wildebeest meat is dried to make biltong, an important part of South African cuisine. The meat of females is more tender than that of males, and is at its best during the autumn season. The wildebeest can provide 10 times as much meat as Thomson's gazelle. The silky, flowing tail is used to make fly-whisks or "chowries".

The gestation period is about 8.5 months, and between 80 and 90% of the calves are born within a 3-week time period. Female wildebeest give birth in the middle of a herd rather than alone, and typically in the middle of the day. This allows time for the newborn to become steady on its feet before night falls and the predators become more active. Calves weigh about at birth, and can usually stand on their own within a few minutes of birth. To escape predation, calves remain close to their mothers for a significant time, and may continue suckling until the next year's calf is nearly due. Some calves leave their mother at about 8 months and form herds with other juveniles. In large female herds, 80% of the wildebeest offspring survive the first month, compared to a 50% survival rate in smaller herds.

Wildebeest provide several useful animal products. The hide makes good-quality leather and the flesh is coarse, dry and rather hard. Wildebeest are killed for food, especially to make biltong in Southern Africa. This dried game meat is a delicacy and an important food item in Africa. The meat of females is more tender than that of males, and is the most tender during the autumn season. Wildebeest are a regular target for illegal meat hunters because their numbers make them easy to find. Cooks preparing the wildebeest carcass usually cut it into 11 pieces. The estimated price for wildebeest meat was about US$0.47 per kilogram around 2008. The silky, flowing tail of the black wildebeest is used to make fly-whisks or "chowries".

The black wildebeest is a gregarious animal with a complex social structure comprising three distinct groups, the female herds consisting of adult females and their young, the bachelor herds consisting only of yearlings and older males, and territorial bulls. The number of females per herd is variable, generally ranging from 14 to 32, but is highest in the densest populations and also increases with forage density. A strong attachment exists among members of the female herd, many of which are related to each other. Large herds often get divided into smaller groups. While small calves stay with their mothers, the older ones form groups of their own within the herd. These herds have a social hierarchy, and the females are rather aggressive towards others trying to join the group. Young males are generally repelled by their mothers before the calving season starts. Separation of a young calf from its mother can be a major cause of calf mortality. While some male yearlings stay within the female herd, the others join a bachelor herd. These are usually loose associations, and unlike the female herds, the individuals are not much attached to each other. Another difference between the female and bachelor herds is the lesser aggression on the part of the males. These bachelor herds move widely in the available habitat and act as a refuge for males that have been unsuccessful as territorial bulls, and also as a reserve for future breeding males.

The calf has a tawny, shaggy coat and weighs about . By the end of the fourth week, the four incisors have fully emerged and about the same time, two knob-like structures, the horn buds, appear on the head. These later develop into horns, which reach a length of by the fifth month and are well developed by the eighth month. The calf is able to stand and run shortly after birth, a period of great danger for animals in the wild. It is fed by its lactating mother for 6-8 months, begins nibbling on grass blades at 4 weeks, and remains with the mother until her next calf is born a year later.
