					Inhabits a lagoon, in clump of Monitpora verrucosa, under rubble and overhangs, and  found along with alpheids (Ref. 101028).  Also occurs in a reef flat at a depth of 9 m (Ref. 100838).  Semicryptic with arms extended in a multidirectional posture, beneath ledges and crevices (Ref. 100368).  Associated with an assemblage of shrimps, a lobster, polychaete, and snail (Refs. 100838, 100851,102275).  Suspension feeder (Ref. 68823).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the class Crinoidea are gonochoric.  During spawning, the pinnule walls rupture and the eggs and sperms are shed into the seawater.  Life cycle:  Embryos elongate into free-swimming larvae (doliolaria) which later sink to the bottom where they metamorphose into stalked sessile crinoid.
