The hamadryas baboon, or sacred baboon, is a large monkey with strong sexual dimorphism. Males have a long light mane on their shoulders and neck that looks like a cape.
The hamadryas baboon differs from other baboons with the light mane of males and a harem system. It helps spread plant seeds and serves as prey for large predators.
