Shellfish coloring pages

Shellfish is a culinary and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some kinds are found only in freshwater. In addition a few species of land crabs such as Cardisoma guanhumi, are eaten, for example in the Caribbean.
Familiar marine molluscs enjoyed as a food source by humans include many species of clams, mussels, oysters, winkles, and scallops. Some crustaceans commonly eaten are shrimp, prawn, lobster, crayfish, and crabs. Echinoderms are not as frequently harvested for food as molluscs and crustaceans, but sea urchin roe is quite popular in many parts of the world.

Most shellfish eat a diet composed primarily of phytoplankton and zooplankton.

Shellfish are among the most common food allergens.
