Is Crustacean vegetarian?

Crustaceans are a large group of arthropods including crabs, lobsters, crayfish, shrimp, krill, and barnacles. As ingredients, crustacean-derived materials include proteins, extracts, chitin, chitosan, and oils. All crustacean-derived ingredients are of animal origin and are neither vegan nor vegetarian.

An ingredient is considered vegetarian if it avoids components derived from killing an animal.
