Crustaceans

Gathers the shellfish with jointed legs and a hard outer shell that are boiled, grilled or used in soups and sauces. It includes shrimp, crab, lobster, crayfish and langoustine. The group does not cover bivalves, snails or squid, which are mollusks, and the general article on crustaceans sits in the general seafood group. Within the Finfish and Shellfish Products subcategory it sits beside the groups Whitefish and Flatfish, Oily and Open-Ocean Fish, Freshwater and Brackish-Water Fish, Bivalves and Sea Snails, Cephalopods and Echinoderms, Roe and Processed Seafood, General Seafood Categories, and each entry is placed in the one group whose description fits it best.
