This neat-looking coral is one of my personal favorites. Diploastrea heliopora is unique and very easy to identify with its cone-shaped corallites having small openings and thick walls. It is also the only species in the genus Diploastrea. Unfortunately this coral is listed by the IUCN to be "near threatened".
Do you see a lot of this coral in your area? Next time you go diving in the Indo-West Pacific, look-out for this massive beauty.
