The venom and the toxicity of Pelagia noctiluca (Cnidaria: Scyphozoa). A review of three decades of research in Italian laboratories and future perspectives

open access: yesJournal of Biological Research, 2015
Recurrent outbreaks of Pelagia noctiluca and health problems consequent to stings were recorded during the last decades. This phenomenon forced some Italian University laboratories to study this cnidarian.

Coral Disease and Health Workshop: Coral Histopathology II [PDF]

open access: yes, 2007
The health and continued existence of coral reef ecosystems are threatened by an increasing array of environmental and anthropogenic impacts. Coral disease is one of the prominent causes of increased mortality among reefs globally, particularly in the ...

The sea anemone Bunodactis octoradiata (Anthozoa: Actiniaria) from southern Patagonia: morphological study and new records [PDF]

open access: yes, 2014
Bunodactis Verril, 1899 comprises at present 19 nominal species of sea anemones. The validity of the genus is under discussion. The description of the species, Bunodactis octoradiata Carlgren, 1899, is insufficient for reliable identification, and ...

Biohybrid Microrobots Based on Jellyfish Stinging Capsules and Janus Particles for In Vitro Deep‐Tissue Drug Penetration

open access: yesSmall Science, Volume 5, Issue 6, June 2025.
This study introduces a biohybrid microrobot utilizing jellyfish‐stinging capsules as nanoinjectors, integrated onto Janus particles. Controlled by magnetic and electric fields, these microrobots achieve deep tissue penetration and precise drug delivery.

Functional and proteomic analysis of Ceratonova shasta (Cnidaria: Myxozoa) polar capsules reveals adaptations to parasitism

open access: yesScientific Reports, 2017
Myxozoa is a diverse, speciose group of microscopic parasites, recently placed within the phylum Cnidaria. Myxozoans are highly reduced in size and complexity relative to free-living cnidarians, yet they have retained specialized organelles known as ...

A genome wide survey reveals multiple nematocyst-specific genes in Myxozoa

open access: yesBMC Evolutionary Biology, 2018
Background Myxozoa represents a diverse group of microscopic endoparasites whose life cycle involves two hosts: a vertebrate (usually a fish) and an invertebrate (usually an annelid worm). Despite lacking nearly all distinguishing animal characteristics,

Sulphate and Chloride-Dependent Potassium Transport in Human Erythrocytes are Affected by Crude Venom from Nematocysts of the Jellyfish Pelagia noctiluca

open access: yesCellular Physiology and Biochemistry, 2013
Background: It has been reported that biologically active compounds extracted from Cnidaria venom may induce damage by oxidative stress. Erythrocytes are constantly exposed to oxidative stresses, which can contribute to sulphydril (SH-) group oxidation ...

Diel activity correlates with colour pattern morphology of heterobranch sea slugs

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1165-1179, June 2025.
The authors show that daytime activity fundamentally shapes the appearance of prey animals to potential predators and that colour pattern phenotypes likely associated with visual signalling are predominantly found in diurnal species of sea slugs. This study showcases novel methodology combining comparative phylogenetic analyses, animal vision modelling,

Novel Polymorphic Microsatellite Markers Reveal Genetic Differentiation between Two Sympatric Types of Galaxea fascicularis. [PDF]

open access: yesPLoS ONE, 2015
The reef-building, scleractinian coral, Galaxea fascicularis, is classified into soft and hard types, based on nematocyst morphology. This character is correlated with the length of the mitochondrial non-coding region (mt-Long: soft colony type, and ...

The Chemical Composition of Sea Nettle Nematocysts

open access: yesExperimental Biology and Medicine, 1969
Interest in the stinging apparatus of the sea nettle (Chrysaora quinquecirrha) has been stimulated recently because of the economic problem produced by this organism. Resort activity is severely curtailed during the summer season when the nettle is prevalent.
