Shellfish were sea creatures. The planet Arkanis was home to gnarled shellfish that was sold as food in Scaparus Port's market. The paralytic shellfish possessed toxin dangerous to humans. Gungans had teeth large enough to crack shellfish.
The human smuggler Nevil Cygni, known as "Nightswan," used shellfish to lead the Chiss Imperial officer Thrawn to crack down on a spice-smuggling ring based on the planet Cyphar.
