Scallop shell. View of a scallop shell, a type of bivalve mollusc. The shell is covered in worm casts and has a barnacle on it at lower centre. The scallop is contained within two of these shells connected together by a hinge (at bottom). The ridged shell is made of minerals containing calcium. The shells are opened and closed by a single muscle. Scallops can swim through the water by rapidly opening and closing their shells.
