The crested mangabey is a rare medium-sized monkey with a noticeable long crest of hair on its head. This species lives only in a narrow strip of forests along the Tana River in Kenya and is endangered.
The crested mangabey differs from other mangabeys with its very long and noticeable crest on the head. It helps disperse tree seeds in the forests of the Tana River and serves as an indicator of the health of this unique ecosystem.
