What is oyester?

An oyster is a marine bivalve mollusk belonging to the family Ostreidae. They are typically found in brackish or saltwater environments and are known for their irregular, hard shells that protect their soft bodies. Oysters are often consumed as food, either raw or cooked, and are also famous for producing pearls, which form when an irritant enters their shell. Additionally, they play a vital ecological role by filtering water and providing habitat for various marine species.
