The Bornean white-bearded gibbon[3] also called the southern gibbon, or Bornean Agile Gibbon, is a species of gibbon native to southern Borneo.
- Unlike other gibbon species, Bornean white-bearded gibbons do not show sexual dimorphism in coloration.
- Males and females look very similar. The coat can vary, but they usually have a brown body with brown legs and arms.
- Their feet and hands are black. The faces of these gibbons are typically framed by white cheeks and eyebrows, often resembling a mustache.
- Their arms, extremely long to their height, allow them to swing quickly in the forest.
