Brachiopods are benthic (bottom dwelling), marine (ocean), bivalves (having two shells). They are considered living fossils, with 3 orders present in today’s oceans. They are rare today but during the Paleozoic Era they dominated the sea floors. Though they appear to be similar to clams or oysters they are not related. They are not even mollusks.The brachiopod shell is a multilayered complex of both organic and inorganic material that has proven to be of fundamental importance in the classification of the phylum. The shells of most rhynchonelliformean brachiopods consist of three layers ( Figure 4 ).
