Feeding Characteristics of Three Species of Intertidal Sea Anemones of the South Kuril Islands

We examined the content of the coelenteron of Oulactis orientalis, Cnidopus japonicus, and Aulactinia sp. (family Actiniidae) inhabiting the intertidal area of Shikotan and Kunashir Islands (South Kuril Islands). The feeding characteristics (food spectrum, the index of filling of the coelenteron, the index of food similarity of the species, occurrence frequency, the index of trophic importance, and the proportions of certain components in the food pellet) allowed us to determine that the examined species are euryphagous.
