Organisms likely to be present on or around coarse sediment are polychaetes (marine worms), small crustaceans such as amphipods (small crustaceans resembling fleas that are important food for fish), cumaceans and tanaids (similar to amphipods), small gastropods (shellfish with a single shell or seaslugs), ophuroids (brittle stars/basket stars), small bivalves (shellfish such as clams), anemones, and sponges. A dominant benthic community supported by a silty/sandy substrate habitat likely includes ophuroids, burrowing anemones, mollusks, sponges, and possible seastars, sea anemones, encrusting sponges, erect sponges, brachiopods and red crab (Chaecon quinquedens).
