Anthozoa | Helioporacea
Ross, M.A. and G. Hodgson. 1981. (Ref. 8294)
Size / Weight / Age
Max length : 100.0 cm COLD male/unsexed; (Ref. 269)
Reef-associated; depth range 0 - 3 m (Ref. 8294)
Climate / Range
Indo-West Pacific: West to Red Sea; north to southern Japan; east to Samoa; and south to New Caledonia.
Forms large colonies, more than 100 cm in diameter, that may be massive, or most commonly, composed of vertical branches or folia. The surface appearance is very smooth, and the color in life is a distinctive grey-brown with white tips. The entire skeleton is blue (Ref. 269).
Depth based from occurrence (Ref. 8294); to be replaced with a better reference. Most common in shallow water (Ref. 269), on reefs at typically less than 2 m. Also in exposed reef areas, reef flats and the intertidal zone (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).
