Molluscs are found in nearly all freshwater and marine environments, and some are found also on land.brachiopod ( plural brachiopods ) Any of many marine invertebrates, of the phylum Brachiopoda, that have bivalve dorsal and ventral shells with two tentacle -bearing arms that capture food.Brachiopods ( / ˈbrækioʊˌpɒd / ), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.The phylum Brachiopoda, or lamp-shells, consists of roughly 400 living and more than 12,000 fossil species of benthic, marine organisms. Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Molecular studies almost unanimously show Brachiopoda as a monophyletic group. between brachiopods and bivalves; however, brachiopods always have different sized valves, and each valve is bilaterally symmetrical.

Brachiopods are a phylum of shelled, marine, invertebrate animals that came into existence during the earliest part of the Paleozoic Era about 520 million years ago and have persisted to present day.

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 . The meaning of BRACHIOPOD is any of a phylum (Brachiopoda) of marine invertebrates with bivalve shells within which is a pair of arms bearing tentacles by which a current of water is made to bring microscopic food to the mouth —called also lampshell.history of the phylum: (1) identifying the origin, morphol-ogy and life modes of the first brachiopods; (2) under-standing the relationships of the major groups to each other and higher sister taxa; and (3) unravelling the roles of the Cambrian and Ordovician radiations that set the agenda for much of subsequent brachiopod evolution.
