Complete Record: The three classes of coelenterates and their characteristics, structure, feeding habits, and reproduction cycles., Uses live-action photography, cinephotomicrography, and diagrams illustrating their activities and bodily structure to show how the classes of coelenterates are distinguished. 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.
