''Bartholomea annulata'' is a species of sea anemone in the family Aiptasiidae, commonly known as the ringed anemone or corkscrew anemone. It is one of the commonest anemones found on reefs in the Caribbean Sea. ==Description== The ringed anemone can reach a diameter of when fully extended. The column is short and wide and the oral disc with its central mouth can be across. There are about two hundred long, translucent tentacles ringed with whorls and spirals formed by groups of cnidocytes. The general colour is grey or brown with the cnidocyte area cream coloured. The anemone contains symbiotic zooxanthellae, single-celled algae that live within its tissues. During the day these use energy from the sun to manufacture carbohydrates by photosynthesis. The sea anemone benefits from this and the algae have a safe lodging free from the likelihood of predation.〔(【引用サイトリンク】title=Corkscrew anemone (''Bartholomea annulata'') )〕
