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. |
