| evidence from hox genes that bryozoans are lophotrochozoans. | bryozoans, or moss animals, are small colonial organisms that possess a suspension-feeding apparatus called a lophophore. traditionally, this "phylum" has been grouped with brachiopods and phoronids because of the feeding structure. available molecular and morphological data refute this notion of a monophyletic "lophophorata." alternative hypotheses place bryozoans either at the base of the lophotrochozoa or basal to the lophotrochozoa/ecdysozoa split. surprisingly, the only molecular data beari ... | 2004 | 15230967 |
