Squids had the ability to eject ink clouds as a defense. Some examples of squids were the star squids, the Utapaun flying squids, and the scum-squids.
The form of the Trident-class assault ship was similar to a squid. The bongo submarine that the Gungans from Naboo employed looked like a strange squid from Naboo or a similar underwater animal. Despite being humanoid, the Quarren from Mon Cala possessed features similar to squids, which led to the offensive nickname "Squid-Heads".
