Animalia > Chordata > Mammalia > Primates > Cercopithecidae > Procolobus > Procolobus verusProcolobus verus (olive colobus)Synonyms: Colobus chrysurus; Colobus cristatus; Colobus verus; Semnopithecus olivaceus The olive colobus monkey (Procolobus verus), also known as the green colobus or Van Beneden's colobus, is a species of primate in the family Cercopithecidae. Its English name refers to its dull olive upperparts. It is the smallest example of all colobine monkeys and is rarely observed in its natural habitat because of its cryptic coloration and secretive nature. It is found in the rain forests of West Africa, ranging from southern Sierra Leone to Nigeria. The olive colobus is classified as near threatened by the IUCN Red List, the cause of its decline attributed to habitat loss and hunting. Though much of the land within the range of the olive colobus has been affected by human activities, it retains its ability to thrive in small degraded forest fragments. |
