The Greysor was a four legged, carnivorous primate from the planet of Naboo. It was long used during hunts and birding parties by the Nabooian aristocracy. Wild greysors hunted in packs of 2 to 12 individuals. They hunted mostly rodents and shaaks, but occasionally scavenged carrion. When hunting, they relied on the sense of sight more than smell. Wild greysors were known to be plagued by fleas. Greysors had nonretractable claws, ideal for running fast. To keep them balanced while running they had an aerodynamic tail.
