A pencil turned upside down is still a pencil, but a sea anemone turned upside down transforms into a jellyfish. Viewers observe the evolutionary transformation of these cnidarians as they diverged into two distinct body shapes, the polyp shape and the medusa shape. After the video, pupils discuss the history of these magnificent animals.
