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.

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.

Flow Structure and Transport Characteristics of Feeding and Exchange Currents Generated by Upside-Down Cassiopea Jellyfish [PDF]

, 2012
Quantifying the flows generated by the pulsations of jellyfish bells is crucial for understanding the mechanics and efficiency of their swimming and feeding. Recent experimental and theoretical work has focused on the dynamics of vortices in the wakes of

A new Byronia species from the Late Ordovician of Estonia [PDF]

Estonian Journal of Earth Sciences, 2016
A new species of a possible thecate scyphozoan Byronia jaegeri sp. nov. is described from the late Katian of Estonia. This new taxon is distinct as it lacks the longitudinal ornamentation present in other Byronia species.

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 ...

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)

Omnivory by the Small Cosmopolitan Hydromedusa Aglaura Hemistoma [PDF]

, 2005
We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter \u3c 4 mm), to determine if it occupies a trophic position similar to that of large medusae.

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 ...

The chromosomal genome sequence of the moon jellyfish, Aurelia sp. 4 Dawson et al. 2005 (Semaeostomeae: Ulmaridae) and its associated microbial metagenome sequences [version 1; peer review: 1 approved, 2 approved with reservations]

Wellcome Open Research
We present a genome assembly from an individual Aurelia sp. 4 Dawson et al., 2005 (moon jellyfish; Cnidaria; Scyphozoa; Semaeostomeae; Ulmaridae). The genome sequence has a total length of 462.10 megabases.

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 ...
