The Importance and Ecology of Bivalves: Clams, Oysters, Mussels, and Scallops Explained.

Bivalves

(clams, oysters, scallops etc) have two shells surrounding the soft mollusk inside

Bivalves are a class of mollusks that includes clams, oysters, mussels, and scallops, among others. They are characterized by having two hinged shells, or valves, that enclose and protect their soft-bodied internal organs. Bivalves are found in a wide range of aquatic habitats, from freshwater ponds to the deepest parts of the ocean, and play an important role in the ecosystems in which they live.

One unique feature of bivalves is their feeding mechanism, which involves filtering water through their gills and trapping small particles of food, such as plankton, algae, and detritus. Bivalves also serve as important food sources for other organisms, including humans. Many cultures around the world consume bivalves as a source of protein and other nutrients.

Bivalves are also important in ecological restoration efforts, as they are often used to improve water quality and provide habitat for other aquatic organisms. Some species of bivalves are also commercially farmed for food or for pearls, which are formed when a foreign object becomes lodged inside the shell and the bivalve secretes layers of calcium carbonate around it to form a pearl.

Overall, bivalves are fascinating and important creatures that play a critical role in aquatic ecosystems and human societies.
