Pale grey in color with distinctive white corallite walls but may also be uniform brown in the western Indian Ocean.

				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.
