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.
