Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 10.5 cm WD male/unsexed; (Ref. 2992)
Up to 10.5 wide, hemispherical, jelly very thick and solid; 8 simple marginal lobes; canals slender, with few anastomoses; mouth-arms like thin, narrow ribbands, margins slightly folded in proximal portions; the sub-genital cavities large, the ostia very small; each marginal sense-club arises from the inner end of a very deep groove and points upward towards the exumbrella.
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
