The Hamadryas were a near-Human species[1] with green skin and slightly ape-like faces.[3] They seemed to not possess the need to blink, and the species lacked a true carotid artery.[4]
The species was named after the Hamadryas baboon;[5] in turn, the name derives from Hamadryads, tree nymphs (a subcategory of dryads) from the Greek mythology.[source?]
As revealed in his Star Wars Blog, Bob Vitas intended that the Hamadryas species to be from a planet called "Papio".[5]
