The Northern Bornean Gibbon (Hylobates funereus), or Grey Gibbon is a small species of the gibbons and is endemic to Borneo. Originally, this species was considered a subspecies of Mueller’s Gibbon (aka Bornean Gibbon) but has been recognized as a distinct species.

Similar to the other gibbon species, they are exclusively arboreal and don’t descend to the ground. They have long arms which helps them swing from branch to branch.
