An evolutionary genomics view on neuropeptide genes in Hydrozoa and Endocnidozoa (Myxozoa)

BMC Genomics, 2021
Background The animal phylum Cnidaria consists of six classes or subphyla: Hydrozoa, Scyphozoa, Cubozoa, Staurozoa, Anthozoa, and Endocnidozoa. Cnidarians have an early evolutionary origin, diverging before the emergence of the Bilateria.

Raising Awareness of the Severity of “Contactless Stings” by Cassiopea Jellyfish and Kin

Animals, 2021
Discussion around avoidance and mitigation of jellyfish stings has traditionally focused on swimmers and divers being mindful of their behavior relative to swimming medusae (pelagic jellyfish).

The first record of the white-spotted Australian jellyfish Phyllorhiza punctata von Lendenfeld, 1884 from Maltese waters (Western Mediterranean) and from the Ionian coast of Italy [PDF]

, 2017
The occurrence of the white-spotted Australian jellyfish Phyllorhiza punctata Lendenfeld, 1884, an Indo-Pacific scyphozoan species mainly restricted to the Levantine Basin, is hereby reported for the first time from Maltese waters (western ...

A Morphospace Exploration Using a General Model of Development Reveals a Basic Set of Morphologies for Early Animal Development and Evolution

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 2, Page 45-58, March 2025.
This work used the model EmbryoMaker to explore the most basic set of morphologies that can be produced from spherical initial conditions by activating cell properties and behaviors in simple genetic territories. We found five possible morphogenetic transformations: invagination, evagination, elongation, condensation and anisotropic growth.

Cytotoxic effect on human keratinocytes of crude extracts from planktonic Cnidaria

Journal of Biological Research, 2009
Biotoxin production is a characterizing aspect of the physiology and ecology of several marine organisms. In this study the cytotoxic effect of crude extracts from jellyfish Pelagia noctiluca, Chrysaora hysoscella and Aurelia aurita (Cnidaria: Scyphozoa)

First records of Phyllorhiza punctata von Lendenfeld, 1884 (Cnidaria, Scyphozoa, Mastigiidae) from Nagasaki and Kagoshima Prefectures, Japan

Check List
Phylllorhiza punctata von Lendenfeld, 1884 originates from Australia and Coral Triangle, but its occurrence has been reported in the Atlantic Ocean and Mediterranean Sea, so it is necessary to better understand its geographic range.

Successful Culture of Pelagia noctiluca (Cnidaria: Scyphozoa) Over Time: A Continuous Supply of the Holoplanktonic Jellyfish for Research and Industrial Applications

Frontiers in Marine Science, 2022
The scyphozoan Pelagia noctiluca has potential value for research and a wide variety of industrial applications. However, its holoplanktonic life cycle makes it difficult to maintain a permanent stock in aquaculture, unlike the continuous supply of newly-

Global Variation in Zooplankton Niche Divergence Across Ocean Basins

Ecology Letters, Volume 28, Issue 2, February 2025.
We explored the evidence of niche divergence between population for marine zooplankton globally. We found 44% of all population comparisons show niche divergence. Niche divergence varied across temperature and bathymetry gradients for copepods. ABSTRACT Modelling responses to climate change assumes zooplankton populations remain similar over time with ...

Hydrozoa e Scyphozoa existentes no Instituto Oceanográfico II [PDF]

Boletim do Instituto Oceanográfico, 1954
In this paper are given distributional records of species already known to frequent brazilian waters. Full description and figures are given of speoies not hitherto known from this coast. Of the mentioned 2O speoies of hydroids, 5 are new for brazilian waters (Eudendrium carneun, E.capillare.
