The Sabah grizzled langur (Presbytis sabana), also known as the Saban grizzled langur, is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of Hose's langur, Presbytis hosei (as Presbytis hosei sabana).[1] [2] The Sabah grizzled langur is native to the island of Borneo in the province of Sabah in Malaysia, with part of its range in Indonesia.[3] It is listed as endangered by the IUCN due primarily to habitat loss, fragmentation and hunting.[3]
The Sabah grizzled langur is mostly gray, with white underparts and black hands and feet.[4] Sabah grizzled langurs range from 48cm (19inches) to 56cm (22inches) long excluding tail and have a tail length ranging from 64cm (25inches) to 84cm (33inches).[4] Males weigh from 6kg (13lb) to 7kg (15lb) while females weight between 5.5kg (12.1lb) and 6kg (13lb).[4]
The Sabah grizzled langur is arboreal and diurnal.[4] It lives in groups of about seven animals including a single adult male.[4] Males who are not part of a group are solitary.[4] It has a varied diet consisting of leaves, fruit, seeds, flowers, insects and bark, and it also consumes mineral-rich mud.[4] It sometimes associates with the maroon langur.[4]
