Hutt

Hutts were a large slug-like sentient species who were native to the planet Nal Hutta. They were well known as galactic gangsters whose Grand Hutt Council controlled the Hutt Clan crime syndicate. One famous Hutt was the crime lord Jabba, who ruled a massive criminal empire from his palace on Tatooine.
