The Roloway monkey lives in groups in mature forests of West Africa. Its gray coat, red rump patch, pale chest fur, and long beard stand out.
Its body is dark gray with a red patch on the lower back. Pale beige fur runs from the chest onto the arms, and it has a pale brow stripe and a long beard.
It is active by day and moves quadrupedally through trees in groups. The account says it tends to travel through the canopy rather than leap from branch to branch.
