Black wildebeest
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.
Bovini
Wild cattle are usually massive bovids that are stout-bodied with thick, short legs. Some species can reach impressive body-sizes such as wild water buffalo and gaur which can weigh between 700 and 1,200 kilograms. The latter species can reach a shoulder height at 2 meters. There even some breeds of domestic cattle that can be even larger than both wild species, one of them being the Chianina which can the bulls can weigh from 1,200 to 1,500 kilograms and reach a similar height to the gaur. There are, however, several species of buffalo that live on the various islands in Indonesia are dwarf species, such as the tamaraw and the anoa, that weigh between 200 and 300 kilograms. Furthermore, not all species of bovin look like cattle, such as the saola which looks more like antelope (a fact that caused some confusion among bovid biologists). What all bovins or wild cattle do have in common is both sexes have the presents of smooth horns, instead of annulated horns seen in most other bovids. In bovinans the horns are round, while in bubalinans they are flattened. Like the spiral-horned antelopes there is extreme sexual dimorphism in bovins, though it is emphasis on the body size and the size of the horns. Males are significantly larger than the females, which most of their features are exaggerated with massive humps, large necks, and in some species the presence of a dewlap. Males and females exhibit sexual monochromatism (with the exception of the banteng, where males are a dark chestnut while females are just chestnut), though the male coloration hues are darker than the females. Coloration can be uniform or with some white markings, from black to brown.
