Life cycle and mating behavior

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.

Netrostoma is a genus of true jellyfish in the family Cepheidae. They are found in the Indo-Pacific. They are sometimes called crown jellyfish, but this can cause confusion with the closely related genus Cephea or the distantly related species in the order Coronatae.
