Mollusks are invertebrate animals with a soft body and a protective shell. They live in the ocean attached to rocks or buried in the sand, like in the case of razor clams and clams. They feed on plankton, an aquatic microorganism, by filtering the seawater. They normally live in regions with temperate climates, as these are the areas where they survive and grow best.
Bivalve mollusks are very important to food culture and gastronomy.
