Numerous (>200) invertebrate taxa were recovered representing hydroids, octocorals, polychaetes, bryozoa, bivalve molluscs, cephalopods, barnacles, isopods, decapod crustaceans, crinoids, asteroids, echiuroids, holothurians, hydrozoans, brachiopods, chitons, gastropods, sponges, and other minor groups.
