Pennant's colobus

Pennant's colobus, also called Pennant's red colobus, Piliocolobus pennantii, is a tree-dwelling primate endemic to tropical Central Africa. Its three traditionally recognised subspecies have an unusually disjunct distribution, with one population on Bioko island in Equatorial Guinea, a second in the Niger River Delta in southern Nigeria and a third in the east-central Republic of Congo, a pattern that has been called a biogeographical puzzle. George Robert Waterhouse described it in 1838 and named it for the naturalist Thomas Pennant. It has a small head, a robust body, long limbs and no thumbs, a head and body length of 53 to 63 cm and a weight of about 7 to 10 kg. It lives in rainforest and marshy forest in troops of twelve to eighty, mainly eating fresh leaves with flowers, fruit and seeds, and it is threatened by habitat loss and bushmeat hunting.
