Shellfish are divided into two main categories - molluscs and crustaceans. Molluscs include uni-valve shells like periwinkles and whelks, bi-valve shells like mussels and oysters, and cephalopods like squid. Crustaceans are mobile creatures with segmented shells such as lobsters, shrimp, crab, and prawns. Finfish are also categorized, including whitefish like cod, haddock and plaice, oil-rich fish such as salmon and mackerel, and cartilaginous fish including sharks.

72. Finfish are occasionally classified in a different way—according
to where they swim in the sea.
Demersal fish are those which live on or near the seabed.
Round and flat whitefish fall into this category.
Pelagic fish swim in mid-waters or near the surface. Examples
are oil-rich fish such as mackerel, herring and tuna.
