Short description Morphology

Up to 18 cm wide, half egg shaped or almost globular; number of velar lappets variable, about 14 in each octant, grooves between them short, all alike; scapules large, extending to or beyond level of bell margin; the free, bifurcate ends of the mouth-arms flare outwards, the lateral branches long.

Biology     Glossary (e.g. epibenthic)

Feeds on bivalve veligers, gastropod veligers, copepod eggs, nauplii, copepodites and adults, and Oikopleura sp. (Ref. 106824). The fertilized egg develops into a tiny, motile planula larva. After swimming freely in the water for several days, the planula attaches to a suitable substrate and transforms into a sessile polyp or scyphistoma. Scyphistomae feed and grow, attaining a maximum size of a few mm. They reproduce asexually a number of ways, including the formation of podocysts and motile or non-motile buds, but only podocyst. The scyphistoma undergoes strobilation which results to ephyrae; developing itself into medusae (Ref. 7696).
