Phylum Porifera - ANSWER simple, sessile (permanently attached to one location) sponges; no tissues, organs, mouth or digestive cavity; filter feeders: flagellated collar cells line the large internal cavity and draw water into the sponge (food particles are strained out of the water current by the collar cells which pass food to other sponge cells); acolemate (no colon); no symmetry; most are marine Phylum Cnidaria - ANSWER class hydrozoa, class scyphozoa, class anthozoa; jellyfish, sea anem...
