The assemblage of Anemonia viridis which is an important component of the photophilic soft algae biocoenosis, has not been adequately studied up to date. The A. viridis assemblage studied, was poor in species number compared to other photophilic soft algae assemblages, possibly because of its peculiar physiology and competition for space. Three age groups of A. viridis were distinguished, two of which (the first and the third) showed significant seasonal variations. The reasons for this are still unclear and may depend on recruitment, competition among small‐sized individuals, predation or other mortality factors, and migration of larger individuals.
