oyster
The common name oyster is used for a number of different groups of bivalve mollusks, most of which live in marine habitats or brackish water. The shell consists of two usually highly calcified valves which surround a soft body. Gills filter plankton from the water, and strong adductor muscles are used to hold the shell closed. Some types of oysters are highly prized as food, both raw and cooked. Other types, such as pearl oysters, are not widely eaten. True (edible) oysters are incapable of making gem-quality pearls, although the opposite idea is a commonly-encountered misapprehension, often seen in illustrations or photographs where an edible oyster shell is mistakenly paired with a gem-quality pearl. The oyster is used as a metaphor in an idiomatic saying, "The world is your oyster", which means that the whole world is laid out before you like a wonderful living buffet.[1] -Wikipedia
