“…As marine systems worldwide continue to decline from local and global physical, chemical, and biological threats (De'ath et al, 2012;Epstein et al, 2016), the need to manage marine natural resources and reduce these threats is becoming increasingly more critical. Early detection and quantification tools are needed to assess risks that can have adverse impacts on the biological, physiological, and metabolic conditions at the level of the organism and the ecosystem (Markert et al, 2003;Downs, 2005).…”

“…Previous studies have indicated jellyfish are able to accumulate trace metals in concentrations exceeding those present in ambient seawater, and concern exists that these could have potential for transfer up food webs (Romeo et al, 1987;Romeo and Gnassia-Barelli, 1992). For example, copper and zinc accumulate in Cassiopea (Templeman and Kingsford, 2010, 2012Epstein et al, 2016) generally within hours to several days and with varying residence times (Fowler et al, 2004), while phosphate concentrations in C. xamachana can reach an order of magnitude greater than those of ambient conditions, even when such levels are undetectable in seawater (Todd et al, 2006). The rapid response of Cassiopea medusae under exposure to metals and nutrients suggests they could serve as a useful indicator tool to detect and quantify short pulses of contaminants/pollutants entering a system, a role achieved by only a few of the current typical biomonitors.…”

“…Additionally, Cassiopea has been presented as a possible model organism for the study of behavioral biology as highlighted by recent developments with sleep behavior (Nath et al, 2017; Figure 1). Likewise, this jellyfish genus has been gaining traction as a biomonitor/bioindicator species, with applications for coastal ecosystem management (Templeman and Kingsford, 2012;Epstein et al, 2016;Klein et al, 2016aKlein et al, , 2017. The relative simplicity of culturing Cassiopea polyps and medusae makes this genus a highly amenable laboratory system.…”

Upside-Down but Headed in the Right Direction: Review of the Highly Versatile Cassiopea xamachana System

The upside-down jellyfish Cassiopea xamachana (Scyphozoa: Rhizostomeae) has been predominantly studied to understand its interaction with the endosymbiotic dinoflagellate algae Symbiodinium. As an easily culturable and tractable cnidarian model, it is an attractive alternative to stony corals to understanding the mechanisms driving establishment and maintenance of symbiosis. Cassiopea is also unique in requiring the symbiont in order to complete its transition to the adult stage, thereby providing an excellent model to understand symbiosis-driven development and evolution. Recently, the Cassiopea research system has gained interest beyond symbiosis in fields related to embryology, climate ecology, behavior, and more. With these developments, resources Ohdera et al. Cassiopea xamachana System Review including genomes, transcriptomes, and laboratory protocols are steadily increasing. This review provides an overview of the broad range of interdisciplinary research that has utilized the Cassiopea model and highlights the advantages of using the model for future research.

“…The articles related to chemical risk highlighted that a careful prior assessment is due to the location of capture and to the breeding of jellyfish. The phenomenon of bioaccumulation, a process through which toxic polluting substances accumulate inside an organism in concentrations higher than those found in the surrounding environment, is typical of the marine species here treated [17,28,29]. For this reason, it is essential to carry out a careful environmental analysis in order to search possible marine pollutants such as pesticides, hydrocarbons, and heavy metals, before marketing jellyfish.…”

FAO (Food and Agriculture Organization of the United Nations) predicted that the world’s population will reach over 9 billion in 2050. This condition will require an increase of the global food production by 60%. Technology and scientific research in the near future will soon be oriented towards optimizing the limited existing resources, reducing waste, and improving the consumption of sustainable new foods. Jellyfish could be a valid alternative among novel food. The purpose of this systematic review was to assess microbiological, chemical, physical, and allergenic risks associated with jellyfish consumption. Four research strings have been used to assess evidences about these risks. PRISMA (Preferred Reporting Item for Systematic Reviews and Meta-analysis) guidelines were applied. Finally, 14 articles were found. Results showed a good level of health safety for jellyfish consumption in terms of its allergenic and microbiological risks. No evidence was found about physical risks. As regards chemical safety, it should be fundamental to carry out a constant monitoring of the water where jellyfish are captured or bred. Periodic checks will be necessary on the finished product, such as the analysis of the aluminum content commonly used during the manufacturing process. The number of publications found was rather small, and further investigation will be necessary to enforce the knowledge on jellyfish consumption by humans.

“…The euryhaline scyphozoan jellyfish Cassiopea maremetens was selected as the target organism as it can be found in lower estuarine systems where salinity is greater than 12 ppt. Recent studies (Epstein et al 2016, Klein et al 2016 have demonstrated that this species responds rapidly to pollutant exposure and is potentially a useful bioindicator of environmental stress. C. maremetens are found in warm coastal regions including sheltered lagoons, estuaries, mangroves, seagrass beds, coral reefs, and mudflats (Drew 1972).…”

Herbicide effects on the growth and photosynthetic efficiency of Cassiopea maremetens

Herbicides from agricultural run-off have been measured in coastal systems of the Great Barrier Reef over many years. Non-target herbicide exposure, especially photosystem II herbicides has the potential to affect seagrasses and other marine species. The symbiotic benthic jellyfish Cassiopea maremetens is present in tropical/sub-tropical estuarine and marine environments. Jellyfish (n = 8 per treatment) were exposed to four separate concentrations of agricultural formulations of diuron or hexazinone to determine their sensitivity and potential for recovery to pulsed herbicide exposure. Jellyfish growth, symbiont photosynthetic activity and zooxanthellae density were analysed for herbicide-induced changes for 7 days followed by a 7 day recovery period. Both the jellyfish and endosymbiont were more sensitive to diuron than hexazinone. The 7-day EC for jellyfish growth was 0.35 μg L for Diuron and 17.5 μg L for Hexazinone respectively. Diuron exposure caused a significant decrease (p < 0.05) in jellyfish growth at 0.1 μg L, a level that is below the regional Great Barrier Reef guideline value. Jellyfish recovery was rapid with growth rates similar to control animals following removal from herbicide exposure. Both diuron and hexazinone caused significant decreases in photosynthetic efficiency (effective quantum yield) in all treatment concentrations (0.1 μg L and above) and this effect continued in the post-exposure period. As this species is frequently found in near-shore environments, they may be particularly vulnerable to herbicide run-off.
