When Competition Breaks the Rules: Feeding Frenzy as a Trigger for Unexpected Fatal Shark Predation Bites on a Human Sea‐User by Non Traumatogenic Carcharinids in the Oriental Mediterranean Open
The fatal shark attack on a male tourist in Hadera (Oriental Mediterranean coast) in 2025 involved several Dusky sharks ( Carcharhinus obscurus ), a species not considered to be traumatogenic to humans. Artificial provisioning in the area …

The Talion law “tooth for a tooth”: self-defense as a motivation for shark bites on human aggressors Open
The concept of “self-defense,” based on aggression by one individual responding to an initial aggression by another, has been observed in several animal taxa such as birds and terrestrial mammals but never documented in detail in sharks. B…

First Evidence of Individual Sharks Involved in Multiple Predatory Bites on People Open
It is widely accepted that populations of terrestrial predators sometimes contain “problem individuals” that repeatedly attack humans, yet this phenomenon has never been demonstrated in sharks. Here, we present photographic and genetic evi…

Use of presence vs absence of symphyseal teeth in jaws for the forensic analysis of bites by large traumatogenic shark species Open
Identifying the species of shark responsible for a bite on humans is both complex and important for understanding and managing the shark risk. Depending on the species, tiny teeth may or may not be present in the symphyseal space at the ju…

Severe cold-water bleaching of a deep-water reef underscores future challenges for Mesophotic Coral Ecosystems Open
Elevated sea surface temperatures are causing an increase in coral bleaching events worldwide, and represent an existential threat to coral reefs. Early studies of Mesophotic Coral Ecosystems (MCEs) highlighted their potential as thermal r…

Behavioural heterogeneity across killer whale social units in their response to feeding opportunities from fisheries Open
Intra‐population heterogeneity in the behavioural response of predators to changes in prey availability caused by human activities can have major evolutionary implications. Among these activities, fisheries, while extracting resources, als…

Toothed whale and shark depredation and bycatch in the longline fishery of French Polynesia Open
Marine megafauna feeding on fishery catches (depredation) or being incidentally caught on fishing gear (bycatch) have become important issues. Their socioeconomic and conservation stakes have been increasingly studied across the world fish…

Marine mammal strandings recorded in New Caledonia, South West Pacific Ocean, 1877 to 2022 Open
Context Strandings are an important source of information for estimating marine mammal biodiversity, particularly in data-sparse ocean basins such as Oceania. Aims Here, we report on knowledge acquired from 218 stranding events recorded in…

Widespread diversity deficits of coral reef sharks and rays Open
A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed global declines o…

Improved Baited Remote Underwater Video (BRUV) for 24 h Real-Time Monitoring of Pelagic and Demersal Marine Species from the Epipelagic Zone Open
Bait-based remote underwater video (BRUV) systems are effective devices for remotely observing fish and other marine organisms in challenging environments. The development of a long duration (24 h) surface BRUV observation surveys allowed …

A review of the behaviours of the Chondrichthyes: a multi-species ethogram for the chimaeras, sharks, and rays Open
In this review of the behavioural patterns of chondrichthyan fishes, we have strived to produce a comprehensive catalogue of events and states and develop standardized terminology. Hence, actions that are slightly different, will be pooled…

The ‘Mistaken Identity Hypothesis’ for shark bites on humans is an anthropomorphic fallacy Open
The Mistaken Identity Hypothesis (MIH) interprets shark bites on surfers, swimmers and snorkelers as ‘mistakes’ stemming primarily from similarities in the visual appearance of ocean users and the sharks typical prey. MIH is now widely acc…

First tiger shark <i>Galeocerdo cuvier</i> bite in 75 years in French Polynesia (Eastern Central Pacific) Open
We analyzed a tiger shark (estimated 2.8 m total length) bite on a snorkeler. The removal of the terminal part of the leg suggests a predatory motivation for the bite. This is the first documented bite by a tiger shark in French Polynesia …
