Maturity: Lm ? range ? - ? cm
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.
