The significance of size-limited predation is that prey and predator can coexist in very intimate proximity, that the surviving prey often attain large sizes and probably make a re- productive contribution disproportionately greater than their abundance, and that these same prey diversify the spatial structure of the environment, usually by adding a vertical dimension not otherwise present.
