Abstract: Interspecific aggression has been observed between the three sea anemones, Metridium senile, Anthopluera elegantissims, and Corynactis californica (Chao, 1975). Intraspecific aggression has been observed between clonal groups in A. elegantissima (Francis, 1973b) and between clonal grooups of M. senile (Purcell, 1977). In asexually produced aggregations of C. californica all the individuals are the same color. Intraspecific interactions were observed in C. californica to determine whether there was aggression exhibited between the colormorphs. The results indicate that avoidance rather than aggression is the most commonly observed response.
