The lophophore ( / ˈlɒfəˌfɔːr, ˈloʊfə -/) [1] is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Hyolitha, and Phoronida, which collectively constitute the protostome group Lophophorata. [2] All lophophores are found in aquatic organisms.Lophotrochozoa was defined in 1995 as the "last common ancestor of the three traditional lophophorate taxa ( brachiopods, bryozoans, and phoronid worms), the mollusks and the annelids, and all of the descendants of that common ancestor". [5] It is a cladistic definition (a node-based name), so the affiliation to Lophotrochozoa of spiralian ... Following recent interpretations of the early Cambrian Protomelission as a soft-bodied bryozoan, our findings add to the evidence of early Cambrian roots for the Bryozoa.
