With plural (or occasionally singular) agreement: a phylum of marine invertebrates comprising the lamp shells, which superficially resemble bivalve molluscs but have a dorsal and a ventral shell valve and two or more crowns of ciliated tentacles (lophophores) that are extended for filter-feeding. Also with plural agreement (also in form brachiopoda): animals of this phylum (collectively or individually); lamp shells.The Brachiopoda were abundant in the Palaeozoic era but are now few in number. Formerly regarded as molluscs, they are now known to be one of the lophophorate phyla.
