This BBC Earth 3.5 minute video may be used as a phenomenon to initiate student three-dimensional thinking about the role of group behavior on both individual and species survival. The video shows cooperative group feeding behavior in several oceanic predators - gannets, dolphins, Bryde’s whales, and sharks - as well as the group avoidance behavior of the target prey - a school of sardines. The phenomenon could engage students along with the following driving questions: What evidence is seen in the film to support the idea that cooperative hunting behavior may benefit the individual and the species? What evidence is seen that cooperative avoidance behavior of the prey may also be beneficial? Do you see any evidence of intraspecific cooperation? How do you think any of these behaviors may have originated? What factors may contribute to the development of cooperative group behavior?
