Keystone species have a disproportionately large effect on their environment relative to their abundance, often by controlling populations of other species, thereby maintaining the balance and diversity of their ecosystem. This can include preying on competitively important species, but they are not necessarily superior competitors, primary producers, or restricted to the intertidal zone.
