Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Occurs in tidepools (Ref. 101028). Subtidal on rocky outcrops at daylight (Ref. 102838). It is usually cryptic under rubble and at the reef during the day (Also Ref. 129602); it gets active at dusk, crawling to exposed perches and spreading its arms in a biplanar posture (Ref. 101028). Also found under dead and living corals (Refs. 100368, 129602). 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.
