By means of extensive numerical simulations, we find that the variety of the population introduces a characteristic scale $R^*$ in its spatial distribution. At scales smaller than $R^*$ the swimmers are homogeneously distributed, while at larger scales an inhomogeneous distribution is observed with a fractal dimension close to what observed for a monodisperse population characterized by mean parameters.
