Freshwater bivalves are mollusks that live in rivers, lakes, and ponds. They have two hinged shells, or valves, that protect their soft bodies. Common examples include clams, mussels, and scallops. These creatures play a vital role in their ecosystems by filtering water, which helps maintain water quality. These bivalves are also important for biodiversity and serve as food for various animals, including fish and birds. Many species are sensitive to pollution and habitat changes, making them indicators of environmental health. Conservation efforts are crucial to protect their habitats and ensure their survival.
