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.here 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. When you look at them, you can see that these body forms are the same except that one is upside down.
