Species CompositionTaxonomic CompositionMegabenthic invertebrates collected in the trawl survey represented 10 phyla, 23 classes, and 127 families (Appendix C-C1, Appendix F-F4, and Appendix F-F5). A total of 325 taxa were collected, which included 308 identified species and 17 identified only to a higher taxa due to damage during collection, and. Of the 308 species, there were 88 mollusks, 76 arthropods, 57 echinoderms, 31 cnidarians, 19 chordates, 10 sponges, 9 ectoprocts, 4 annelids, 4 brachiopods, and 2 echiurans. The most diverse classes were Malacostraca, with 71 species, Gastropoda with 69 species, and Anthozoa with 26 species. The most diverse families were Majidae (spider crabs; 13 species), Trochidae (top snails, 9 species), and both Hippolytidae and Crangonidae (shrimps), with 7 species each. A number of the species encountered had not previously been taken in either routine POTW monitoring or regional synoptic monitoring efforts. Several of the species given provisional names appear to be new species both to the SCB fauna, and to science. Table V-7.
