						Colony: massive. Corallites: circular, closely compacted in shallow water, more widely spaced in deeper water. Septa: fine, numerous, regular. Paliform lobes often poorly developed. Color: pale gray, green or brown, often with calices of contrasting color (Ref. 848).					
				
				
						
			
			
			
			
				
					Depth range is based on occurrence.  Minimum depth from Ref. 115203. Occur in all reef environments (Ref. 848), subtidal on rocks, rocky reefs, outer reef channel, back and foreslopes and in lagoons (Ref. 98471).  Depending on water conditions, can be found encrusting in small colonies, or forming massive heads (Ref. 130769).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					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.
