Crustacean Sauces

Crustaceans are members of the subphylum Crustacea, a Latin word that means “shell.” Crustaceans have jointed bodies, appendages (which may be legs), and antennae. Mollusks, including clams, mussels, scallops, oysters, snails, squid, and octopus, have unsegmented bodies and thus are classified differently from crustaceans, though both groups are considered shellfish.
