Resumen:
Despite the ecological and socio-economical importance of Rhizostomeae jellyfishes little is knownabout their feeding strategies and diet. We described the consumption of different ephyrae speciesby different developmental stages of Lychnorhiza lucerna medusae in laboratory conditions. This isthe first report of a rhizostome medusa feeding on gelatinous preys. Besides, L. lucerna seems tobe capable of avoiding cannibalism. Finally, we discuss the importance of gelatinous zooplanktonas prey items for scyphozoan ephyrae, considering their limited capacity of capturing fast-escapingcrustacean prey.
