Single Swarm (image) Michigan State University Caption The picture is of a single swarm that evolved in the model due to predation in the presence of the predator confusion effect. If you think of each white line as a fish or bird (prey) and the red line as the predator, you can see this as a "top-down" view of the swarm if you were looking over them.
