Diploastrea heliopora occurs in the tropical Indo-West Pacific Ocean in a depth range from 3-15m from the Red Sea  and East Africa to Western Australia, to the Ryukyu Islands and Fiji. This is one of the most easily recognised and least variable of all massive corals. The diameter of a single corallite is 8-10 millimetres. Diploastrea heliopora forms dense, robust, dome-shaped coral colonies. This slow-growing (2 to 6 mm/year) coral has the potential to yield continuous paleoclimate records spanning up to 1000 years for the warmest waters on Earth, the Indo-Pacific Warm Pool, and has a long fossil history as a single recognizable species. \nThe foto was taken in day time, the tentacles are retracted, as they extended only at night. \nSoanggi Island, Banda Sea, Indonesia 4°19'34.3773 S 129°42'21.3856 E at 14m depth
