About this species

Tubastraea micranthus, commonly known as the Black sun coral, is a coral from the Tubastraea genus, which comprises the sun corals. They have a dark green color and they grow and branch out in bush/tree like colonies. The habitat of T. micranthus ranges from the Red Sea to Madagascar, and into the Pacific as far as Fiji. It has been observed in waters as shallow as 4m to a depth of 138m in the new habitat. It is notable though, that in its native habitats Tubastraea micranthus has only been found at depths up to 50 meters and any discovered at lower depths are in invasive environments. Furthermore, there have been obscure sightings of Tubastraea micranthus in Korea.
