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

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.

Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish Species

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors.

Techniques and Advances in Ultrafast Photography

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...

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 ...

Associations between fishes (Actinopterygii: Teleostei) and anthozoans (Anthozoa: Hexacorallia) in epipelagic waters based on in situ records

open access: yesJournal of Fish Biology, Volume 107, Issue 6, Page 2166-2172, December 2025.
Abstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.
