Where seen? This hard coral that forms thin cup-shaped colonies is sometimes seen on our Southern shores.

Features: Colonies up to 15-20cm, generally a very thin plate (0.2-0.5cm) forming a cup or inverted cone. Sometimes, the edges are slightly wavy.

Corallites tiny (less than 0.2cm) low rounded bumps with a large depression in the centre where the polyps sit. Corallites generally spaced apart with a smooth surface between them. Polyps tiny with few tentacles, usually only seen at night. Colony colours seen include yellow, brown, green and bluish, edges may be pale or in a different colour.

Turbinaria reniformis, Turbinaria mesenterina and Turbinaria frondens may have these features.
