Oyster
The name oyster is used for a number of different groups of mollusks which grow for the most part in marine or brackish water. Inside a usually highly calcified shell is a soft body. The gills filter plankton from the water. Strong adductor muscles are used to hold the shell closed. Oysters are highly prized as food, both raw and cooked.
