The Zanibar, in a particular rite, participated in consuming other beings.
The act of a sentient species consuming others of their own kind, often due to scarce food resources or times of starvation, was known as Cannibalism. This term was also applied when individuals or entire species consumed members of other sentient species.
The One, a Rakatan, infamously forced numerous species into engaging in this practice. The insectoid Colicoids were notorious for cannibalism, devouring off-worlders who happened to land on their homeworld, and sometimes capturing vessels that ventured too closely. The reptilian Marits also traditionally practiced cannibalism; however, they consumed only those who had already died, viewing it as a way to dispose of the bodies that benefited the living.
Certain Hutts had a reputation for eating their enemies, including Jabba Desilijic Tiure.
The Zanibar, working for Grappa the Hutt, were known to perform ritualistic sacrifices where they consumed other sentient beings.
During the rise of the Galactic Empire, a Human named Dezono Qua was a known cannibal; he would purchase slaves at market and then have his droid prepare them as food.
Bossk, the Trandoshan bounty hunter, displayed cannibalistic tendencies. Besides enjoying Zanibar and Wookiees, he devoured his siblings before they hatched and, later in life, his own father.
On the planet Tatooine, some Human cannibals were known to wander both the cities and the wilderness.
