This is the classic "table" coral, with long-lived colonies forming tables several metres in diameter. The coral is supported by a central stalk; the main braches anastomose in the horizontal plane, while secondary branchlets all grow vertically to the same height, forming a flat surface (Ref. 269).
Common at shallow to intermediate depths throughout its range (Ref. 269). Upper reef slopes; outer reef flats (Ref. 846). Has very high bleaching level and estimated mortality nearing 100% in Palau (Ref. 66144). Hermaphroditic (Refs. 97272, 113708, 113712) (Ref. 113708). Spring to summer (Ref. 113712).
