  abstract = {{I}dentifying ontogenetic changes in jellyfish diet is fundamental to understand trophic interactions during their life cycle. {S}cyphomedusae blooms exert major predation pressure on plankton communities, although their role in ecosystems has long been misrepresented. {T}his study assesses seasonal and ontogenetic changes in the diet of the scyphomedusa {R}hizostoma pulmo, one of the largest yet overlooked {M}editerranean jellyfish. {M}edusae gut contents (n = 127) were collected during one year in {B}ages {S}igean lagoon, southern {F}rance. {R}esults show that the diet composition differs from the availability of prey in the environment with contrasting preferences along ontogeny. {C}alanoid (70%) and harpacticoid (45.8%) copepods were the most frequent prey and the major carbon contributors for small medusae (bell diameter < 15 cm). {I}n contrast, ciliates (43.5%) were the most frequent prey for large organisms (> 15 cm), which obtain most of their carbon intake from ciliates and fish eggs (20.9%). {T}he overall impact on micro and mesozooplankton showed that small medusae consume 5% of the copepods daily standing stock, while large medusae consumed 8% of ciliates daily standing stock. {O}ur results stress that {R}. pulmo display different trophic pathways along its life cycle, firstly interacting with the classical food web, and shifting afterwards to a greater interaction with the microbial loop.},
