The branch Eumetazoa, as we have seen above, consist of metazoans with organs, a mouth and digestive cavity These can be divided into two groups: Radiata and Bilateria. Radiata are charactrised by radial (or biradial) symmetry; they have tentacles and a limited number of organs. They have also a digestive cavity with mouth opening to the exterior. The Radiata include two Phyla : Cnidaria and Ctenophora. The Bilateria are bilaterally symmetrical animals and include the rest of the eumetazoans.
