Discussion
- This entry is about mudusae only; no mass of reproduction info available for the polyp stage
- Reproductive output is underestimated because ephyra is large relative to neonate planula
Facts
- eggs remain in the medusae till the 18 d of planula, which encyst before forming a polyp (planulocysts) (Ref: Brew1989)
- Feeds mainly on copepods during max growth (Ref: Brew1989)
- Polyp also produces cysts (stimulated by increase of temp) from which new polyps develop (podocysts); decrease of temp stimuates excystment ofpodocysts and the strobilation of polyps (Ref: BrewFein1991)
