Veron, J.E.N. and G. Hodgson. 1989. (Ref. 8817)
Size / Weight / Age
Reef-associated; depth range 0 - 40 m (Ref. 848)
Climate / Range
Tropical; 31°N - 34°S, 26°E - 176°E (Ref. 848)
Indo-Pacific: widespread in East Africa including the Red Sea to New Caledonia, north to Ryukyu Islands, south to Great Barrier Reef, Australia.
Formation: phaceloid to plocoid, with few to numerous corallites. Corallites are less than 7 mm diameter. Septa: mostly in two cycles, with only the first reaching the columella; primary septa may be exsert. Poorly developed columellae. Mantles extend during the day and may form a continuous surface obscuring the underlying growth-form. Color: commonly dark red with obvious green oral discs, also pink, orange, brown or uniform dark grey with white margins to primary septa (Ref. 848).
Occurs in reef environments where water is turbid (Ref. 848). Also in deep, steep slopes and crevices (Ref. 98471). Members of the class Anthozoa are either gonochoric or hermaphroditic. Mature gametes are shed into the coelenteron and spawned through the mouth. Life cycle: The zygote develops into a planktonic planula larva. Metamorphosis begins with early morphogenesis of tentacles, septa and pharynx before larval settlement on the aboral end (Ref. 833).
