However, the valves of a lamp shell cover the top and bottom of the animal, while those of a clam cover the right and left sides. Furthermore, the internal anatomy of brachiopods does not resemble that of pelecypods; the two groups are not related. There are two classes in the phylum: the Inarticulata, members of which have the valves held together by muscles alone, and the Articulata, members of which have interlocking processes that form a hinge.
