Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Inhabits the infrastructure of reefs (Ref. 800). Found in a lagoon, under rubble, coral overhangs, and on fore reefs under crevices at night (Ref. 101028). Also beneath ledges, pinnacle overhangs on reef slope and among coral branches. May be cryptic or semicryptic (Ref. 100368). A host to a diverse assemblage of symbionts (Ref. 101028). Feeds on plankton and detritus (Ref. 800).
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.
