Description
Description
The ringed anemone can reach a diameter of 30 centimetres (12 in) when fully extended. The column is short and wide and the oral disc with its central mouth can be 12 centimetres (4.7 in) 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.
