Phylum Mollusca, Class Bivalvia

Bivalves

Mollusks with left & right shells called valves attached by a hinge.  The muscular foot is reduced in some families.  Sessile species are typically attached to the substrate by tough byssal threads.  They feed by filtering phytoplankton & bacteria from the water column and may not be safe to consume after blooms of toxic dinoflagellates, sometimes referred to as red tides.
