The Zanibar, in their practices, would ritually consume other beings.
The act of consuming one's own kind, or other sentient species, is referred to as Cannibalism, often arising from circumstances like food scarcity or widespread famine. This term also applies when individuals or entire species ingest other sentient species.
The One, a Rakatan figure, compelled numerous species into practicing cannibalism. The insectoid Colicoids were notorious for their cannibalistic behavior, devouring off-world visitors to their homeworld and sometimes seizing vessels that ventured too close. The reptilian Marits also had a tradition of cannibalism, but they only consumed the dead, viewing it as a way to dispose of the remains that would benefit the living.
Certain Hutts were known to consume their adversaries, including Jabba Desilijic Tiure.
The Zanibar, working for Grappa the Hutt, engaged in ritualistic sacrifices where they consumed other sentient beings.
A Human named Dezono Qua, alive during the rise of the Galactic Empire, was a known cannibal; he would procure slaves from the market and have his droid prepare them as food.
Bossk, a Trandoshan bounty hunter, displayed cannibalistic tendencies; he enjoyed the taste of Zanibar and Wookiees, and he also devoured his siblings before they hatched, and later, his own father.
Some Human cannibals were known to exist within the cities and wilds of the planet Tatooine.
