Size / Weight / Age
Max length : 100.0 cm male/unsexed; (Ref. 269)
Reef-associated; depth range 1 - 15 m (Ref. 100937)
Climate / Range
Tropical; 36°N - 27°S, 34°E - 180°E (Ref. 847)
Colonies form large plates covered with thin, high collines that form radiating valleys. The plates may be more than 1 m in diameter while the colonies may reach several centimeters in height. Corallites are widely spaced with septocostae continuous between them (Ref. 269). Zooxanthelate (Ref. 19).
Maximum depth from Ref. 98471. Common from below the reef flat to the limit of coral growth (Ref. 269). Also in lower reef slopes and turbid water (Ref. 98471). Has high bleaching level and high estimated mortality in Palau (Ref. 66144). Hermaphroditic (Ref. 113712). 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).
