Kingdom Animalia, Phylum Cnidaria The phylum Cnidaria includes organisms with a variety of radially symmetrical forms; all are carnivores. The life cycle of some cnidarians includes both a medusa (jellyfish) stage and a polyp (attached) stage. Medusae are usually free-floating, and often produce gametes. Polyps are fleshy columns with an attachment at one end and a mouth and tentacles at the other end.
Cnidaria. Cnidaria is a phylum of animals, which contains amazingly beautiful coral reefs, electrifying jellyfish, and many other interesting oceanic creatures. There are about 10,000 species of cnidarians and all of them are unique among all other organisms for the presence of the Cnidocytes. Cnidaria and porifera are two different phyla. â¢ Cnidarians have Cnidocytes but not the poriferans. â¢ Cnidarians have well-organized organ systems but not the poriferans; on the other hand, poriferans have an efficient tunnel system made up of pores but not the cnidarians.
