This arboreal monkey lives in coastal West Africa. It forms groups, eats fruits and leaves, and uses calls to signal danger and other cues.
Its back is brownish gray and its underside tawny brown. White brows and whiskers frame a dark face, and its long, slender tail is dark.
It is active by day in social groups in trees. Members groom one another and forage for fruits, leaves, seeds, and other foods.
