Why do marine endotherms eat gelatinous prey?
TLDR
It is proposed that in line with research from terrestrial ecosystems atypical food items might be beneficial to the consumers in a non-energetic context, encompassing self-medication, and responding to homeostatic challenges.
Review of jellyfish trophic interactions in the Baltic Sea
ABSTRACT Despite the diversity and oftentimes large biomass of jellyfish in marine systems, their ecological role remains poorly understood. We here provide the first systematic review of studies on…
The importance of jellyfish–microbe interactions for biogeochemical cycles in the ocean
Jellyfish blooms can represent a significant but largely overlooked source of organic matter (OM), in particular at the local and regional scale. We provide an overview of the current state of…
Microbial Processing of Jellyfish Detritus in the Ocean
TLDR
It is shown that about half of the jelly-OM is instantly available as dissolved organic matter and thus, exclusively and readily accessible to microbes, which implies that a major fraction of the detrital jelly-om is rapidly incorporated into biomass by opportunistic bacteria.
Trophic separation in planktivorous reef fishes: a new role for mucus?
TLDR
A previously undocumented anatomical adaptation in the mouths of fairy wrasses is revealed: the mucosa throughout the buccal cavity is packed with goblet cells, enabling it to secrete large quantities of mucus in this region; a new trait that, until now, had not been documented in wrasses.
The utility of jellyfish as marine biomonitors.
Microplastic ingestion in jellyfish Pelagia noctiluca (Forsskal, 1775) in the North Atlantic Ocean.
Powering Ocean Giants: The Energetics of Shark and Ray Megafauna.
Integrating siphonophores into marine food‐web ecology
Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column. We (1) synthesize current…

Ecological and Societal Benefits of Jellyfish
TLDR
This discussion ranges from the role of jellyfish in carbon capture and advection to the deep ocean through to the creation of microhabitat for developing fishes and the advancement of citizen science programmes.
Jellyfish as an alternative source of food for opportunistic fishes
Jellyfish and other gelata as food for four penguin species – insights from predator‐borne videos
TLDR
It is emphasized that gelatinous organisms actually represent a widespread but currently under-represented trophic link across the southern oceans, even for endothermic predators, which have high energetic demands.
A jellyfish diet for the herbivorous green turtle Chelonia mydas in the temperate SW Atlantic
TLDR
This study finds that animal matter, in particular gelatinous plankton, was consumed in large proportions compared to herbivorous food items such as terrestrial plants and macroalgae in the diet of the neritic green sea turtles.
Jellyfish on the menu: mtDNA assay reveals scyphozoan predation in the Irish Sea
TLDR
It is shown that jellyfish predation may be more common than previously acknowledged: uncovering many previously unknown jellyfish predators.
High occurrence of jellyfish predation by black‐browed and Campbell albatross identified by DNA metabarcoding
TLDR
It is demonstrated here that dietary DNA metabarcoding enables measurements of the contribution of gelatinous zooplankton to the diet of marine predators.
Ecological and Economic Consequences of Ignoring Jellyfish: A Plea for Increased Monitoring of Ecosystems
Gelatinous zooplankton can dominate the dynamics of marine ecosystems; can have major ecological, social, and economic impacts; are often indicative of broader ecosystem perturbations; and are…
Organism life cycles, predation, and the structure of marine pelagic ecosystems
TLDR
It is proposed that future research might profitably be directed toward the question of how the pelagic environment selects for life histories and morphologies of organisms under conditions when resource availability and predation are both significant structural buttresses.
The jellyfish buffet: jellyfish enhance seabird foraging opportunities by concentrating prey
TLDR
It is concluded that jellyfish provide feeding opportunities for diving seabird by concentrating forage fish, and that the impacts of jellyfish on marine ecosystems are more complex than previously anticipated and may be beneficial to seabirds.
Rapid scavenging of jellyfish carcasses reveals the importance of gelatinous material to deep-sea food webs
TLDR
It is shown from baited camera deployments in the Norwegian deep sea that dense aggregations of deep-sea scavengers can rapidly form at jellyfish baits and consume entire jellyfish carcasses in 2.5 h, suggesting that the contribution of gelatinous material to organic fluxes may be seriously underestimated in some regions.
