 Phoronids, brachiopods and bryozoans (ectoprocts) are collectively called lophophorates, because all feed using lophophores.From about the 1940s to the 1990s, family trees based on embryological and morphological features placed lophophorates among or as a sister group to the deuterostomes, a super-phylum that includes chordates and echinoderms.In the early development of their embryos, deuterostomes form the anus before the mouth, while protostomes form the mouth first.
