Jellyfish and other pelagic gelatinous organisms (“gelata”) are increasingly perceived as an important component of marine food webs but remain poorly understood. Their importance as prey in the oceans is extremely difficult to quantify due in part to methodological challenges in verifying predation on gelatinous structures. Miniaturized animal-borne video data loggers now enable feeding events to be monitored from a predator's perspective. We gathered a substantial video dataset (over 350…

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…
A Paradigm Shift in the Trophic Importance of Jellyfish?
Unravelling the macro-evolutionary ecology of fish–jellyfish associations: life in the ‘gingerbread house’
TLDR
It is found that jellyfish association is a probable adaptive anti-predator strategy for juvenile fish, more likely to evolve in benthic, benthopelagic, and reef-associating species than those adapted to other marine habitats.
Molecular Analysis of Predator Scats Reveals Role of Salps in Temperate Inshore Food Webs
High precision, high coverage DNA-based diet analysis tools allow greater insight into the food web interactions of cryptic taxa. We used DNA faecal-metabarcoding to look for unrecorded taxa within…
An Overview of the Medusozoa from the Southwestern Atlantic
Medusozoans are critical components of coastal and marine ecosystems. They are ubiquitous, living from the surface to the bottom layers of the world’s oceans and tolerating a wide range of…
In situ observation of a record-sized squid prey consumed by a Gentoo penguin
TLDR
A squid (probably Greater hooked squid, Onykia ingens) with an estimated mantle length of 240 mm was consumed whole after a period of competition over the prey item with another foraging Gentoo penguin at sub-Antarctic Marion Island.
Molecular approach indicate consumption of jellyfish by commercially important fish species in a coastal Mediterranean lagoon.
Deep pelagic food web structure as revealed by in situ feeding observations
TLDR
This work quantitatively characterize the deep pelagic food web of central California within the California Current, complementing existing studies of diet and trophic interactions with a unique perspective, and highlights key interactions within the poorly understood ‘jelly web’.
Life beneath the ice: jellyfish and ctenophores from the Ross Sea, Antarctica, with an image-based training set for machine learning
TLDR
This study constitutes the first optics-based survey of gelatinous zooplankton in the Ross Sea and the first study to use in situ / in aqua observations to describe taxonomic and some trophic and behavioural characteristics of jellyfish and ctenophores from the Southern Ocean.

On the significance of Antarctic jellyfish as food for Adélie penguins, as revealed by video loggers
TLDR
Video-monitored prey intake of a key predator indicates that Adélie penguins occasionally feed on jellyfish, even though other prey types are also available, and refining the perception of scyphozoans' niche may help anticipate the functional response of the food webs to the extensive changes witnessed in the Antarctic environment.
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.
Predation on pelagic coelenterates: a review
  • M. Arai
  • Environmental Science
    Journal of the Marine Biological Association of the United Kingdom
  • 2005
TLDR
Coelenterates (cnidaria and ctenophores) are well recognized as predators in food webs of marine ecosystems but are less often considered as prey but may provide sources of energy comparable to better recognized prey such as arthropods.
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.
Gelatinous plankton: irregularities rule the world (sometimes)
TLDR
How life cycle patterns are central in marine ecology, as are the pulses of gelatinous organisms, are described, and how such a dramatic lack of knowledge can affect the authors' understanding of the marine ecosystem as a whole is highlighted.
Massive Consumption of Gelatinous Plankton by Mediterranean Apex Predators
Stable isotopes of carbon and nitrogen were used to test the hypothesis that stomach content analysis has systematically overlooked the consumption of gelatinous zooplankton by pelagic mesopredators…
Questioning the Rise of Gelatinous Zooplankton in the World's Oceans
TLDR
It is concluded that the current paradigm in which it is believed that there has been a global increase in gelatinous Zooplankton is unsubstantiated, and a strategy for addressing the critical questions about long-term, human-related changes in the sea as they relate to gelatinousZooplanka blooms is developed.
The secret lives of jellyfish
TLDR
Long regarded as minor players in ocean ecology, jellyfish are actually important parts of the marine food web and contain more calories than some other jellyfish.
Adélie Penguin Population Diet Monitoring by Analysis of Food DNA in Scats
TLDR
The diverse prey identified by this DNA-based scat analysis confirms that the generalist feeding of Adélie penguins makes them a useful indicator species for prey community composition in the coastal zone of the Southern Ocean.
Recurrent jellyfish blooms are a consequence of global oscillations
TLDR
All available long-term datasets on changes in jellyfish abundance across multiple coastal stations are analyzed, using linear and logistic mixed models and effect-size analysis to show that there is no robust evidence for a global increase in Jellyfish abundance.
