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.
Black colobus
The black colobus monkey is a large species with a head-body length of 50–70 cm and a long tail of around 80 cm. As in all "Colobus" species, the black colobus has a slender build and ischial callosities - tough pads of skin on the rump. There is little sexual dimorphism between the two sexes - adult males can weigh between 10–15 kg, whilst females weigh between 10–11 kg. The black colobus is covered in black fur apart from the ears and face, and has longer hairs on its cheeks and forehead. Unlike other species of colobus monkey, black colobuses have no white markings. The two subspecies of black colobus look very similar, although the fur of "Colobus s. satanas" is slightly longer and fluffier. There is currently not enough data to estimate the life expectancy of the species.
