The phylum Cnidaria comprises a wide array of both solitary and colonial invertebrates, or invertebrate animals which form increasingly large colony structures as they grow. Jellyfish, corals, anemones, and hydrozoans are examples of Cnidarians. Their body is either sacklike, hollow, and tentacled or umbrella-shaped and tentacled, as well as the ability to sting prey. While corals do attack prey with stingers, they derive much of their energy from carbon-releasing algae which live in their body. Reefs are the secreted exoskeletons of the living coral (Loren Babcock 1996, “Phylum Cnidaria”). This specimen is a colonial coral.
