The barnacle Chthamalus stellatus is capable of growing at depths much lower than those at which it is actually found in nature. Experimental studies have determined that the lower limit of Chthamalus is determined by another barnacle, Balanus balanoides. The rapidly growing Balanus is able to smother, crush, or undercut the slower-growing Chthamalus. Because of this, Chthamalus cannot survive in the lower depths where Balanus is found. The interaction between these two barnacles is an example of
