What is an "oyster"?

An oyster is a bivalve mollusk that inhabits both freshwater and saltwater environments. They have rough, irregular-shaped shells that are typically grayish or brown in color. Oysters are known for forming reefs or beds where they cluster together in large numbers. They are filter feeders, drawing in water and extracting nutrients such as plankton and organic matter. Oysters are important for maintaining water quality as they can filter significant volumes of water. They are also valued for their culinary appeal and are considered a delicacy in many cuisines. Oysters can be enjoyed raw, cooked, or used in various dishes such as soups, stews, and seafood platters.
