Biology     Glossary (e.g. epibenthic)

Small individuals of this species are found attached to filamentous algae, while larger ones are attached to a variety of algae by means of its adhesive disc on the base of their peduncle. It detaches and reattaches by somersaulting using their adhesive organs. Found at depths of 1 to 8 m. Feeds on small crustaceans, fly larvae, polychaetes and gastropod molluscs. Preyed upon by fish and nudibranchs (Ref. 87801). Members of the class Scyphozoa are gonochoric. Life cycle: Egg is laid by the adult medusa which later develops into a free-living planula, then to a scyphistoma to a strobila, and lastly to a free-living young medusa (Ref. 833).
