抄録: Distribution pattern, reproductive mode and aggressive behavior of the sea anemones Anthopleura uchidai and A. asiatica from rocky coast of Kochi were studied. Anthopleura uchidai occurred on the crevices and hollows of rocks in splash area and A asiatica did on the underside of stones in intertidal area. The frequency of occurrence in aggressive response between two neighbor individuals differed between species was higher in A. uchidai than in A. asiatica, suggesting that sexual reproduction might be dominant in A. uchidai while A. asiatica might frequently perform asexual reproduction. Anthopleura uchidai more often used acrorhagi for aggression than A. asiatica. Distances between individuals and between colonies were similar between the two species, although A. uchidai formed larger colony than A. asiatica. This suggests that dominant reproductive mode and the intensity of aggressive interaction might not affect local distribution pattern in the two sea anemones.
