Appearance

The colouration varies between subspecies, being black or some shade of brown with chestnut-brown or reddish face, arms and legs and pale underparts. The black face is crowned with long hair, usually parted in the middle.

Pennant's red colobus is a moderate-sized species with a head and body length of 53 to 63 centimetres (21 to 25 in) and a tail of 60 to 70 centimetres (24 to 28 in). It weighs about 7 to 10 kilograms (15 to 22 lb).

Range and habitat

Pennant's red colobus is found in several locations in western Central Africa. The nominate subspecies, P. P. Pennantii is endemic to Bioko, an island 32 kilometres (20 mi) off the coast of Equatorial Guinea. The monkeys are largely restricted to the south-west part of the island and have a total range of less than 500 square kilometres (190 sq mi).

Three subspecies have traditionally been recognised but their distribution is peculiarly disjunct and has been considered a biogeographical puzzle, with one population on the island of Bioko (Equatorial Guinea), a second in the Niger River Delta in southern Nigeria, and a third in the east-central Republic of Congo.
