Like all black-and-white colobi, the Angola colobus has black fur and a black face, surrounded by long, white locks of hair. It also has a mantle of white hair on the shoulders. The long, thin tail can be either black or white, but the tip is always white. There is a significant regional variation in the total amount of white on the body and the length of the fur. Animals that live in the mountains have longer, thicker fur than animals from the lowlands to protect them against the cold.
The Angola colobus has a head-body length of 50 to 70 cm, with the males usually being larger than females. The tail is about 75 cm long, and the body weight varies between 9 and 20 kg.
Distribution and habitat
The Angola colobus occurs in dense rainforests, both in the lowlands and coastal mountains. It lives in most of the Congo Basin, to the south and northeast of the Congo River, as far as Ruwenzori, Burundi and southwestern Uganda. The species can also be found in East Africa, especially in the montane and coastal forests of Kenya and Tanzania and in isolated mountain areas. Although the species is named after Angola, it is quite rare in that country. Of all Colobus species, the Angola colobus occurs in the southernmost latitudes. The geographical range lies south of that of the mantled guereza. It is found up to 2,415 m above sea level in Kenya.
The diet of the Angola colobus consists of about two thirds of leaves and one third of fruit and seeds. The East Tanzanian population lives mainly on ripe fruit, supplemented with full-grown leaves.
