Phylum Brachiopoda. Brachiopods were much more diverse and common in the past than they are today. They live attached to surfaces on the seafloor and filter the food they need from passing water. Because they have two valves, they are sometimes mistaken for bivalves (Phylum Mollusca), but are not at all similar in terms of their soft part anatomy.The origin of the brachiopods is uncertain; they either arose from reduction of a multi-plated tubular organism, or from the folding of a slug-like organism with a protective shell on either end. Since their Cambrian origin, the phylum rose to a Palaeozoic dominance, but dwindled during the Mesozoic .Historically the Phylum for the brachiopod has been divided into two classes: Articulata and Inarticulata. This is in reference to how the two shells are ...Brachiopod Internal Morphology Morphology Brachiopods have been separated into two classes, the ARTICULATA and the INARTICULATA but there are enough similarities in their general morphology to consider them together.
