''Arca'' is a genus of saltwater clams in the family Arcidae, the ark clams. Description As is typical for ark clams, species in this genus have a long, straight hinge line. Some species in this genus, such as ''Arca zebra'' and ''Arca noae'', have a brown-and-white striped pattern. ''Arca'' attach themselves to rock with byssal threads which protrude through a gap on the ventral (open) side.

Valve (mollusc)
A valve is each articulating part of the shell of a mollusc or another multi-shelled animal such as brachiopods and some crustaceans. Each part is known as a valve or in the case of chitons, a "plate". Members of two classes of molluscs, the Bivalvia (clams) and the Polyplacophora (chitons), have valves. Species within one family of very unusual small sea snails, marine opisthobranch gastropods in the family Juliidae, also have two articulating shells or valves, which resemble those of a bivalve. This exceptional family is commonly known as the bivalved gastropods. Gastropods in general are sometimes called "univalves", because in those that have a shell, the shell is usually in one part. Chitons The valves of chitons are eight dorsal, articulated shell plates, which are frequently coloured and sculpted. After death the girdle that holds the plates together disintegrates and the plates separate. Thus individual plates can be found washed up in beach drift, as shown in t ...
