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.
