Description Most bivalves are marine and there are no terrestrial forms. Bivalve is the second most
dominant class in the phylum Mollusca. Bivalves are characterized by a laterally compressed
body with an external shell of two halves that is hinged dorsally. The bivalve hinge has sets
of interlocking teeth that prevent valves from sliding along each other. The valves are united
dorsally by elastic, a partially calcified or chitinous external or internal ligament and are held
together by one or two adductor muscles. The head is rudimentary and have lost the buccal
or radular apparatus. The mantle lobes are either connected or free ventrally. They are mostly
ciliary feeders, with sieving and sorting mechanisms on labial palps and leaf-like ctenidium.
The mantle cavity includes a pair of ctenidia suspended laterally. The mouth and anus are
located at opposite ends of the body and the gut is typically convoluted. The foot is
compressed and adopted for burrowing, except in sedentary forms where it is rudimentary.
