The o'cerry was a non-sentient herbivore species native to the Expansion Region moon of Alchenaut. Discovered and named by Jedi biologist Bowspritz at some point prior to 990 BBY, the species was noted for its habit of acting as a predator alarm for other herbivores in the ecosystem. Bowspritz included o'cerry in the "Galactic Bestiary" section of The Jedi Path: A Manual for Students of the Force, which introduced the species to numerous generations of Jedi trainees.
