7.7 Phylum Brachiopoda. Brachiopods are shelled, filter-feeding marine organisms (Figure 7.30) that inhabit the seafloor and come in various shapes and sizes. They have been around since the Cambrian with incredible diversity during the Paleozoic Era (Figure 7.31). Brachiopods are still around today, but their diversity is greatly diminished. 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 . Despite many major advances in recent years, three key challenges remain in bringing clarity to the early history of the phylum: (1) identifying the origin, morphology and life modes of the first …

Even though they are not closely related to bivalve mollusks (such as clams or mussels), brachiopods look and act like bivalve mollusks. Specifically, brachiopods suspension feed, secrete calcium carbonate shells with two valves that hinge together in some species, and attach ...
