As in many other species, dominance relations are strongly correlated with body size (beetles, Beebe, 1947; lobsters, Fielder, 1965; voles and deermice, Grant, 1970). Aggression is most intense between individuals of similar size and least intense between individuals most dissimilar in size (Noble, 1939; Collias, 1944; Miller, 1964; Coates, 1977). The importance of size in the dominance relations of damselfish may result from size-dependent competition for certain resources. Individuals of different 134.
