Individuals have gathered palatable oysters for thousands of years. Pearl oysters, processing valuable pearls, have a place with a divided clan that is just indirectly identified with them.
Edible, or true, oysters are bivalves (two-shelled mollusks related to clams and mussels). Like other bivalves they have no head or brain, and live quiet lives on the sea floor. They food by drawing momentums of ocean water into their forms, from which they sift out little nourishment particles.
