New Insights into the Toxin Diversity and Antimicrobial Activity of the “Fire Coral” Millepora complanata

open access: yesToxins, 2022
To date, few studies have been carried out aimed at characterizing the toxins synthesized by hydrocorals of the genus Millepora. The purpose of this study was to explore the toxin diversity and antibacterial activity of the “fire coral” M.

THE NEMATOCYST TOXIN OF METRIDIUM

open access: yesThe Biological Bulletin, 1971
1. Material discharged by isolated nematocysts of Metridium senile senile Linnaeus (1767) has been found to be toxic to crayfish Orconectes virilis Hagen (1870), O. propinquus Girard (1852), and Procambarus econfinae Hobbs (1942).2. The toxin appears to be composed of a proteinaceous, undialyzable fraction, and a dialyzable fraction containing two ...

Tentacle Transcriptome and Venom Proteome of the Pacific Sea Nettle, Chrysaora fuscescens (Cnidaria: Scyphozoa)

open access: yesToxins, 2016
Jellyfish venoms are rich sources of toxins designed to capture prey or deter predators, but they can also elicit harmful effects in humans. In this study, an integrated transcriptomic and proteomic approach was used to identify putative toxins and their

Functional Characteristics of Nematocysts Found on the Scyphomedusa Cyanea Capillata [PDF]

open access: yes, 2007
Although prey capture by cnidarians is mediated through nematocysts, their influence on prey selection by cnidarians remains poorly documented. The difficulty in visualizing nematocyst–prey interactions remains the chief obstacle to understanding how the

Functional Morphology and Fluid Interactions During Early Development of the Scyphomedusa Aurelia aurita [PDF]

open access: yes, 2009
Scyphomedusae undergo a predictable ontogenetic transition from a conserved, universal larval form to a diverse array of adult morphologies. This transition entails a change in bell morphology from a highly discontinuous ephyral form, with deep clefts ...

Insights into individual variations in nematocyst venoms from the giant jellyfish Nemopilema nomurai in the Yellow Sea

open access: yesScientific Reports, 2019
The giant jellyfish, Nemopilema nomurai, is widely distributed from the Eastern China Sea to the northern part of the Yellow Sea and has resulted in numerous hospitalizations in coastal areas of China, especially in Northern China.

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,

Jellyfish stings‐induced cardiac failure was ameliorated through AAG‐mediated glycogen‐driven ATP production

open access: yesExploration, Volume 5, Issue 1, February 2025.
Single cell sequencing revealed AAG, an energy regulatory protein targeting to glycogen, was highly expressed in jellyfish stings‐induced CF patients. We postulated AAG could increase glycogen metabolism, protecting against jellyfish stings‐induced CF.

Stephanthus antarcticus, a new genus and species of sea anemone (Actiniaria, Haloclavidae) from the South Shetland Islands, Antarctica [PDF]

open access: yes, 2003
Stephanthus antarcticus gen. nov. et sp. nov. is described and illustrated from six specimens collected in the Antarctic Peninsula on the Polarstern cruises ANT XV/3 and ANT XIX/3. The new genus is characterised by the absence of sphincter and basilar

The hydroid and medusa of Sarsia bella sp. nov. (Hydrozoa, Anthoathecatae, Corynidae), with a correction of the life cycle of Polyorchis penicillatus (Eschscholtz)

open access: yesScientia Marina, 2000
A new hydrozoan, Sarsia bella sp. nov. is described in both its hydroid and medusa stage from north of Puget Sound, Washington in the San Juan Islands, USA and off the southernmost tip of Vancouver Island, Canada.
