BIVALVES

 

As the name suggests, bivalves are two separate shells or valves joined by a hinge and ligament. They are the second largest class of shells after the Gastropods with approximately 10,000 species identified to date. Some families are very popular with collectors, including the exquisite Spiny Oysters, the delicate Tellins, and the richly colored and patterned shells of the Pecten,Venus and Cockle families.
