Family Dendrophylliidae

Where seen? This hard coral that forms thick encrusting plates is sometimes seen on many of our Southern shores.

Features: Colonies up to 15-30cm, sometimes larger. Generally a thick (about 1cm) encrusting plate that follows the contours of the surface.

Corallites small (0.5cm) smooth rounded bumps or conical with a large depression in the centre when the polyp is retracted, sometimes just a depression. Corallites generally spaced apart with a smooth surface between them. Polyps tiny rather transparent, usually only seen at night. Colony colours brown, yellowish brown, pinkish beige sometimes with a greenish sheen. The margins usually not in a different colour.

Turbinaria irregularis and Turbinaria stellulata may have these features.
