We examined competition between different size classes of the limpet Cellana tramoserica at two locations in southeastern Australia. At Williamstown, on a sheltered basalt shore, small limpets showed the same competitive superiority over larger conspecific individuals as has been reported previously. In contrast, when the experiment was repealed on a limestone shore (Cheviot Beach), this pattern disappeared, and there were strong interactions within size classes, but weak interactions between size classes. Large limpets lost weight as density rose, while small limpets lost weight and had a higher risk of mortality. Intra-class interactions at Cheviot Beach were generally weaker than inter-cl..
