4Characteristics Marine animals adapted for life on the ocean floor Lophophore- a ciliated ring of tentacles that surround the mouth and is specialized for capturing suspended particles in the water.Often asexual reproductionU shaped gut
5Body forms Brachiopods Resemble clams and other bivalve mollusks because the body is enclosed between two shellsDiffer because shells are dorsal and ventral instead of lateral.Attach to substrate by a long stalkLophophore
7Body forms cont. Phoronids and Bryozoa A “crown” of tentacles-lophophorebuild upright tubes of chitin to support and protect their soft bodies.
8FeedingCilia on the lophophore beat, this brings water laden with food into the mouth or opening. This allows them to filter the food they need out of the water.
9Secretion and Gas Exchange Phoronids secrete tubes of sediment and live in them, extending their lophophores from their tubes for feedingNearly all secrete outer casings (shells, tubes, exoskeletons)Bryozoa: gasses are exchanged through body surface, especially the tentacles
10ReproductionBryozoa form sessile colonies by asexual budding or by statoblast production.Statoblast- small seedlike structureReproduction in all lyphophorate phyla is often asexual reproduction.
