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.
Cnidarians are classified into four main groups: non-moving (sessile) Anthozoa (sea anemones, corals, sea pens); Cubozoa (box jellies);swimming Scyphozoa (jellyfish); and Hydrozoa, a broad group that includes all the freshwater cnidarians as well as many marine forms.There are about 10, 000 species of Cnidarians.nidaria is a phylum containing over 9,000 species found only in aquatic and mostly marine environments. All cnidarians have radial symmetrical. There are two major body forms among the Cnidaria-the polyp and the medusa. Sea anemones and corals have the polyp form, while jellyfish are typical medusae.
