| Ruffled
disk coral Turbinaria sp.* Family Dendrophylliidae updated Nov 2019 Where seen? This hard coral that forms ruffled plates is sometimes seen on our Southern shores. Features: Colonies up to 15-30cm, generally a thin plate (0.5cm), with edges that are folded and highly ruffled. Some may form untidy cups or encrust the inside of shallow gaps. Corallites small (0.2cm) conical. Corallites generally spaced apart with a smooth surface between them. Polyps tiny with many tentacles, usually only seen at night. Colony colours seen include brown, green often with edges in a different colour. Turbinaria reniformis, Turbinaria mesenterina and Turbinaria frondens may have these features. Coral homes: Small animals are sometimes seen sheltering within the folds. Circular or oval bumps with a small slit in the centre are sometimes seen among the polyps and even on the underside. Are these barnacles? |
