Individual cells within a dense swarm. a Trajectories of fluorescently labelled cells. b The mean-squared displacement shows super-diffusive behavior. Each line shows the statistics obtained for a single cell. c Following proper scaling, the displacement of positions of cells (along the x or y axes) collapse on a master curve which is approximately a Lévy stable law. d A trajectory of a single bacterium showing the instantaneous cell-orientation, velocity and the flow around it
