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.

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)

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 ...

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 ...

A Network Approach to White Band Disease Challenged Staghorn Coral Acropora cervicornis microRNAs and Their Targets

Ecology and Evolution, Volume 15, Issue 4, April 2025.
Our study looks at the association between microRNA expression and disease resistance in Caribbean staghorn corals infected with White Band Disease. We find three microRNAs differentially expressed due to disease resistance with putative targets involved in innate immunity.

Multigene phylogeny of the scyphozoan jellyfish family Pelagiidae reveals that the common U.S. Atlantic sea nettle comprises two distinct species (Chrysaora quinquecirrha and C. chesapeakei) [PDF]

PeerJ, 2017
Background Species of the scyphozoan family Pelagiidae (e.g., Pelagia noctiluca, Chrysaora quinquecirrha) are well-known for impacting fisheries, aquaculture, and tourism, especially for the painful sting they can inflict on swimmers. However, historical

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.
