Rhizostomins: A Novel Pigment Family From Rhizostome Jellyfish (Cnidaria, Scyphozoa)

Frontiers in Marine Science, 2021
Many pigments, such as melanins, are widely distributed throughout the animal kingdom. Others have arisen as novelties in particular lineages, for example, the Green Fluorescent Protein (GFP) found in cnidarians.

Asexual reproduction strategies and blooming potential in Scyphozoa [PDF]

Marine Ecology Progress Series, 2014
Scyphistomae show different modes of propagation, occasionally allowing the sudden release of great numbers of medusae through strobilation leading to so-called jellyfish blooms. Accordingly, factors regulating asexual reproduction strategies will control scyphistoma density, which, in turn, may influence blooming potential.

Diel and Artificial Light Effects on Nearshore Communities Revealed by eDNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Environmental DNA revealed rapid, taxon‐specific community reorganization across diel and artificial light conditions in a nearshore marine ecosystem. Distinct responses among trophic groups indicate that artificial light at night reshapes predator–prey interactions and community structure within 30 min of exposure.

Development and evaluation of a novel COI targeting primer set for metabarcoding-based enhanced detection of Scyphozoa (Cnidaria: Medusozoa) species

Scientific Reports
Many jellyfish species within the Scyphozoa exhibit seasonal blooms, particularly in summer, resulting in significant economic losses for fisheries and posing direct health risks to humans from toxins in their nematocysts.

Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Jellyfish (Chrysaora lactea, Cnidaria, Semaeostomeae) aggregations in southern Brazil and consequences of stings in humans

Latin American Journal of Aquatic Research, 2014
The frequency of jellyfish blooms is generating a world-wide discussion about medusae population explosions, mainly those associated with stings. We report over 20,000 envenomations caused by Chrysaora lactea (Scyphozoa) in the State of Paraná (southern ...

First record of the association between Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) and Cyrtograpsus affinis (Decapoda, Varunidae) Primer registro de la asociación entre Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) y Cyrtograpsus affinis (Decapoda, Varunidae)

Latin American Journal of Aquatic Research, 2012
We report the association between the jellyfish Lychnorhiza lucerna and the crab Cyrtograpsus affinis. Numerous examples of associations between medusae and brachyurans have been observed in the field and noted in the literature.
