Kingdom Animalia, Phylum Cnidaria The phylum Cnidaria includes organisms with a variety of radially symmetrical forms; all are carnivores.

Polyps are fleshy columns with an attachment at one end and a mouth and tentacles at the other end.
Jellyfish, corals, and other stingers. Cnidarians are incredibly diverse in form, as evidenced by colonial siphonophores, massive medusae and corals, feathery hydroids, and box jellies with complex eyes. Yet, these diverse animals are all armed with stinging cells called nematocysts.Cnidarians are united based on the presumption that their nematocysts have been inherited from a single common ancestor. The name Cnidaria comes from the Greek word cnidos, which means stinging nettle.nidarians are incredibly diverse in form, as evidenced by colonial siphonophores, massive medusae and corals, feathery hydroids, and box jellies with complex eyes.
