Siderastrea siderea

(Ellis and Solander, 1786)

Colonies are encrusting to massive and are usually over one metre across. Corallites are 3-4.5 millimetres diameter, with numerous septa tightly compacted giving a smooth surface. Septa are uniformly separated and reduce in number from the wall to the columella without forming many fan-like fusions.

Colour: Usually light reddish-brown.

Habitat: Shallow reef environments.

Abundance: Common.
