This gibbon lives in northern and eastern Borneo and travels through the canopy using its long arms.
It has a blackish-brown crown, underside, and inner limbs, a broad white brow, pale cheek patches, and darker hands.
Pairs duet at dawn and move hand-over-hand through the canopy. They eat fruit, especially figs, as well as leaves and insects.
