Hard Clam (Mercenaria mercenaria) : It is an edible bivalve marine mollusc. Their shells bar distinctive markings. The accumucation of toxin produces by marine algae refered as \" Red tide\" affect these clams. These toxins affect human Central nervous system. Flat Tree Oyster (Isognomon alatus): The main external feature is that it is sculptured by a large number of concentric rings with loose flakes and varies in colour from plae brown olive to purple black. Filter feeder, drawing water into shell and passes it through its gills extracting plankton and small organic matter. Mossy Ark (Arca Imbricate): They vary both in size and shape. The shell is striped with, tinted with or completely colored arich brown.The shell of most species has a top shell layer that is thick brown periostracum affixed to the hard calcareous part of the shell. Common Jingle (Anomia Simplex): Jingle shell are flat and round and are often found in the company of or attached to American oysters. The lower valve is anchored to a rock or hard substrateby byssal threads secreted by a gland near the jingle shell\'s foot , passing through a hole in the botton valve. Doc Bales Ark (Barbaria Tenera): Found along the Atlantic coast of North America ranging from Suth Florida to West Indies. Coquina (Donax variablitis): Edible salt water clams.Known for their highly varible color patterns. Found just buried under the surfsce of sandin the wave-swept area of the beach known as the swash zone. Butter cup lucine (Anodontia alba): The exterior is smooth and white and is etched with fine concentric lines running parallel with the margin which show the animals annual growth stages.The interior of the valve is buttercup yellow.The parallel line formed by the attachment of mantle muscles can be seen running parallel with the margin with the two muscle scars near the hinge.
