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)

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.

Macroscale abundance patterns of hydromedusae in the temperate Southwestern Atlantic (27º-56º S) [PDF]

, 2019
Gelatinous organisms are crucial components of marine ecosystems and some species imply social and economic consequences. However, certain geographic areas, such as the temperate Southwestern Atlantic (SWA, 27 - 56 S), remain understudied in terms of ...

Water Interaction Type Affects Environmental DNA Shedding Rates of Terrestrial Mammal eDNA Into Surface Water Bodies

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Although shedding rates for aquatic species are well studied, little is known about terrestrial mammal shedding rates in water. In this study, we quantify eDNA shedding rates from domestic dogs during various interactions with water bodies and find that defecation and crossing through water produce the highest shedding rates, highlighting direct water ...

Morphological diversity of medusan lineages constrained by animal–fluid interactions [PDF]

, 2007
Cnidarian medusae, commonly known as jellyfish, represent the earliest known animal taxa to achieve locomotion using muscle power. Propulsion by medusae requires the force of bell contraction to generate forward thrust.

Understanding Dynamic Molecular Responses Is Key to Designing Environmental Stress Experiments: A Review of Gene and Protein Expression in Cnidaria Under Stress

Molecular Ecology, Volume 34, Issue 9, May 2025.
ABSTRACT Gene and protein expression analyses are powerful tools to investigate the responses of cnidarians to stress, providing information on both genetic and functional variation and capturing dynamic shifts in organismal physiology. As the use of high throughput sequencing to understand responses of cnidarians to stressors is still relatively new ...

Interannual size changes of adult Aurelia sp.5 medusae stage in the Marine Protected Area of Mljet Island South Adriatic [PDF]

, 2012
Aurelia aurita s.l. is the most widespread scyphozoan jellyfish that recurrently appear "en mass" and forms large aggregations mainly in coastal waters, embayments and estuaries.

Comparative Aspects of Structure and Function of Cnidarian Neuropeptides

Frontiers in Endocrinology, 2020
Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and ...

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.
