(a) Two types of shell fish
Crab
Prawn (lobster, shrimp, crayfish, oyster or mussel also acceptable)
(b) Three classes of fish
White fish: These are lean fish that store their oil in the liver rather than the flesh, so the flesh is white and low in fat. Examples are cod, sole, hake and whiting.
Oily (fatty) fish: These have oil distributed throughout the flesh, which is usually darker and richer. Examples are mackerel, herring, sardine and salmon.
Shell fish: These have a hard outer shell instead of a backbone. They include crustaceans such as crab, lobster and prawn, and molluscs such as oyster and mussel.
