Habitat Type: Marine
Comments: Occupies depth range from 0-50 m, but typically occurs between 15-30 m on fore-reef communities on bank reefs and fringing reefs (Goreau and Wells, 1967; Adey, 1977; Tunnicliffe, 1983).
Goreau and Wells (1967): 0 to 50 m (15-30 m optimum depth). Goldberg (1973a): outer reef platform (16-20 m). Gilmore and Hall (1976): patch reefs. Adey (1977): major mid-depth (10-25 m) reef builder. Cairns (1982): back reef to outer ridge. Davis (1982): octocoral-dominated hardgrounds. Tunnell (1983): occupies most extensive depth range (0-30 m) in genus. Jaap (1984): bank reefs and transitional reefs. Wheaton and Jaap (1988): spur and groove reefs, back reef.
