Phylum porifera (sponges: sessile, most simple multicellular organisms, no organs, central body cavity, pores incurrent water, still animals, still regulate their body. Fact: if a sponge is broken up into tiny pieces, each piece would grown into another grown sponge. Phylum cnidaria: jellyfish, corals or anemones, can be floating (freeswimming jellyfish) Medusae: corals & anemones polyps. More sessile, but still have central body cavity within each of them.
