Oysters are a type of shellfish found in both saltwater and freshwater environments. They have a hard, protective shell that opens to reveal a soft, edible body inside. Oysters are often enjoyed raw on the half shell, cooked in various dishes, or used to make oyster stew. They are known for their unique, briny flavor and are considered a delicacy in many cultures. In addition to being tasty, oysters are also nutritious. They are rich in zinc, iron, and omega-3 fatty acids, making them a healthy choice for seafood lovers. Furthermore, oysters play an important role in their ecosystems by filtering water and providing habitat for other marine life.
