Description
Siderastrea siderea is a colonial coral that forms low domes or boulder-shaped structures with a smooth dimpled surface as much as 2 metres (6 ft 7 in) wide on the seabed. It can be encrusting when young. The corallites, the calcareous cup-shaped depressions in which the polyps sit, are about 5 millimetres (0.20 in) wide with about 50 or 60 little ridges called septa. The general colour is reddish brown. This species can be confused with the closely related lesser starlet coral (Siderastrea radians) but that is usually smaller and has deeper, more angular corallites, each with 30 to 40 septa.
