| Ruffled
disk coral Turbinaria sp.* Family Dendrophylliidae updated Nov 11 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 small (about 1cm) with many short tentacles, usually only seen at night. Colours seen include brown, green often with edges in a different colour. Coral homes: Small animals are sometimes seen sheltering within the folds. Lesions are sometimes seen among the polyps and even on the underside. These look like they harbour some sort of animal, perhaps a barnacle? |

 Is this a barnacle growing in the coral? |
