Sea slug

Sea slugs or sea-slugs were creatures that lived in seas. Decades after 382 BBY, the Scalvi Carli and Tren were playing amongst themselves re-enacting their uncle Bree Menaren's famed encounter with members of the Crulkon species. As Tren—who was playing as Menaren—pretended to stab Carli who was playing as a Crulkon, they told them to "die, Crulkon sea slug!" In 34 ABY, the Ace Squadron pilot Hype Fazon compared his teammates to sea slugs and threatened to leave the squadron if his squadron leader Jarek Yeager continued to make him work with them.

The Mon Calamari Rask Odai disliked children, and he compared them to sea slugs.
