Describes the characteristics of the phylum Coelenterata, including fresh and salt water examples; shows the typical coelenterate body plan; and provides examples of the three classes of coelenterates. Shows how coelenterates obtain and digest their food, how they reproduce by sexual and asexual processes, and how they move. Identifies and shows examples of the three classes of coelenterates: Hydrozoa, Scyphozoa, and Anthozoa. Pictures the hydra as a general representative of the phylum, describing it in detail and viewing experimentally its reaction to the chemical glutathione. Views reproduction in hydra.
