They seem to be closer to Trochozoa than to Ecdysozoa or Deuterostomia in most molecular analyses. Alas, the bryozoan genome is as derived as its morphology, making it a difficult subject for molecular methods. Sep 17, 2009 · So bryozoans are important in a kind of ecosystem way. Experiments have shown that some corals, at least, if you lower the pH in which they live, they thrive just fine. They live, they grow, they reproduce – they just don’t make a skeleton.
