Semibalanus balanoides is a types of large barnacle, adapted to living within deep water whereby it is seldom exposed to air. Chthamalus stellatus is a slightly smaller species, living in both deep and shallow water and also capable the withstanding exposure to air which causes dehydration. Methodical removal the each species from one area is maybe to display that the smaller species could accounting shallow and deep area in the lack of the big species. However, when smaller varieties are removed, the larger varieties do not occupy the shallow zone. In the natural setting when both varieties are present, the bigger S.balanoides outcompete the smaller sized C.stellatus because that resources and space, and the smaller types do not inhabit the deeper zone; this is called competitive exclusion. The an essential niche of the 2 barnacles overlaps in the depths zone, back the actual niche that the smaller varieties can only be realized in the shallow zone. In contrast, the fundamental niche that the huge species is met in its establish niche.
