Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Inhabits live or dead corals in shallow water (Ref. 800). Under overhangs (Ref. 10128). Also on reef slope; on rubble and sandy bottom. Usually semicryptic in reef crevices (Ref. 100368). Known as a host to various crustaceans (Refs. 100838, 102275). Seen among alpheids, pontoniines, galatheids, and myzostomes (Ref. 101028). 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.
