Könsmognad: Lm ?  range ? - ? cm Max length : 2.8 cm WD hane/ej könsbestämd; (Ref. 800)

Biologi     Ordlista (t.ex. epibenthic)

The maximum size refers to disc diameter. The arm length is measured at 18 cm (Ref. 128807). Occurs beneath coral slabs and in holes and crevices; also in branching corals (Ref. 800). They are also found at the reef edge, with a sandy, rubble, and dead coral substrates (Ref. 87041), also in silty, seagrass, sandy rocky, algal mats, hydroids, Thalassia beds and coral reefs (Ref. 128807). Feeding as juveniles may be facilitated through parasitic feeding (Ref. 102357).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae

Members of the class Ophiuroidea are mostly gonochoric, others are protandric. Fertilization is external. Brooding is common, bursae is used as brood chambers where the embryos develop into juveniles and later crawl out from the bursal slits. Life cycle: Embryos hatch into free-swimming planktotrophic larvae and later metamorphose into tiny brittle stars which sink down the bottom where they grow into adult form.
