Description
Color: Usually uniform cream or grey, sometimes greenish.

Colonies are dome-shaped with a very even surface and may be up to 2 m high and 7 m in diameter. The skeleton is very dense. Corallites are plocoid. Columellae are large. Septa are equal and are thick at the wall and thin where they join the columellae. Polyps are extended only at night. Colonies are distinctive, massive, and often exceed 1 metre across. Corallites are round and closely packed, and formed by extratentacular budding. They are 8 to 10 mm diameter. The most characteristic feature of Diploastrea heliopora is its corallite wall structure. Walls are not solid but are delineated or formed by the thickened outer ends of the septa, which are not attached to each other laterally. This feature can even be detected beneath the tissue of the live corals.
