Another 15,000 species are known only from fossils. As with brachiopods and phoronids, bryozoans possess a peculiar ring of ciliated tentacles, called a lophophore, for collecting food particles suspended in the water.Marine Invertebrates. Many marine invertebrates (animals without backbones) are found in the intertidal zone: on rocky and sandy substrates in regions accessible during low tide. Most of these intertidal species are found in the subtidal zone as well; this area is usually submerged, but may be exposed during extremely low tides.Bryozoans have a ring of ciliated tentacles that gather food called a lophophore and have a U shaped digestive system. Whereas cnidarians have just one opening for both intake of materials and expelling waste.Identification: Pectinatella magnifica is a species of freshwater bryozoan in the class Phylactolaemata.
