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

$This Acropora table coral was seriously damaged, but the colony is regrowing over the damaged table. The white edges are the growing zones. \nObviously this colony has a high recovery potential and over all the resilience of the reef is exceptional: \nWhen the Banda volcano last blew its top in 1988, a large lava flow swept down the northern slope into the ocean, covering a large part of reef in volcanic rock. What many thought would be the total destruction of the reef has instead become one of the most incredible coral reefs in Indonesia. Measured from ground zero after the eruption in 1988, this particular reef is known to be the fastest growing coral in the world. \nLava Flow, Banda Neira Island, Indonesia, \n4°30'20.418 S 129°52'57.456 E at 9m depth$

Tubastrea, also known as sun coral or sun polyps, is a genus of coral in the phylum Cnidaria. It is a cup coral in the family Dendrophylliidae.
