About

Galaxea astreata is a common and cosmopolitan large-polyp scleractinian coral of the Indo-Pacific, for which WoRMS gives the Japanese name Ogasawara azami sango; in English it is the octopus, starburst or scalpel coral. It is the most abundant coral species in the Xuwen Coral Reef National Nature Reserve in China. Colonies may be sub-massive, columnar or encrusting, and large ones exceed two metres. The calcium carbonate skeleton is distinctive, with plate-like corallites set well apart from one another, and the polyps are pink, grey, green or brown. It occurs from 1 to 30 m, most commonly around 15 m, and prefers clear salt water to turbid brackish water. Unlike most corals, which feed at night, it expands its polyps by day to take zooplankton and coral larvae and contracts them at night. It is a broadcast spawner, and colonies may be hermaphroditic or gonochoric. As a scleractinian it is on CITES Appendix II.
