Mollusks: soft sea animals that fall into three main categories: Univalves, which have a single shell (such as abalone and conch) Bivalves, which have a pair of hinged shells (such as clams and oysters) Cephalopods (such as octopus, squid and cuttlefish) 2. Crustaceans: animals with segmented shells and jointed legs 26 Shellfish Classification
