When many individual organisms come together and move as one entity, that’s a swarm. From a handful of birds to billions of insects, swarms can be almost any size. They have no leader, and members interact only with their neighbors or through indirect cues. Members follow simple rules: travel in the same direction as those around you, stay close and avoid collisions. Maria R. D’Orsogna shares why.
