Introduction
Ocean biologist by education, Bernard Séret is an ichthyologist specialized in the study of the chondrichthyan fishes (sharks, rays and chimaeras). He worked at the “Institut de Recherche pour le Développement” (IRD) for almost 40 years, and had been hosted by the “Muséum national d’Histoire naturelle, Paris” for about 20 years. Retired since 2015, he continues his scientific work and carries out consultancies.

Despite the fact that elasmobranchs are now targeted in artisanal fisheries in the wake of continuous declines of teleosts in Ghana, data on any aspects of these fisheries are poor. This study aims to document the spatial and temporal variation, and biological composition of elasmobranchs in five key elasmobranch-dominated fishing communities in We...

Sharks have declined worldwide and remote sanctuaries are becoming crucial for shark conservation. The southwest Indian Ocean is a hotspot of both terrestrial and marine biodiversity mostly impacted by anthropogenic damage. Sharks were observed during surveys performed from April to June 2013 in the virtually pristine coral reefs around Europa Isla...

The Mediterranean Large Elasmobranchs Monitoring (MEDLEM) database contains over 3000 records (more than 4000 individuals) of large elasmobranch species from 20 different countries around the Mediterranean and Black seas, observed from 1666 to 2017. The main species included in the archive are the devil fish (1 813 individuals), the basking shark (...
Article
The epithet obsolerus recently used to name a new species of shark is doubtless an “incorrect original spelling” which must be corrected into obsoletus. However, a strict respect of Article 32.5.1 of the Code would not allow this correction, as the original paper did not provide “clear evidence of an inadvertent error”, which can be established onl...

Developing nations in tropical regions harbour rich biological resources on which humans depend for food, income and employment, yet data to aid their management is often lacking. In West Africa, the diversity and fisheries of elasmobranchs are poorly documented, despite them being known to be economically important and vulnerable to overexploitati...

Accurate determination of the origin and timing of trauma is key in medicolegal investigations when the cause and manner of death are unknown. However, distinction between criminal and accidental perimortem trauma and postmortem modifications can be challenging when facing unidentified trauma. Postmortem examination of the immersed victims of the Y...

The alpha taxonomy of the globally distributed shark genus Squalus has been under intense investigation recently, and many new species have been described over the last decade. However, taxonomic uncertainty remains about several taxa. Without consistent nomenclature and the ability to reliably distinguish between the different Squalus species, bas...

Four species of stingrays of the genus Dasyatis occur in the Gulf of Gabès, but the taxonomic status of one of them, D. tortonesei has been questioned by several authors, and synonymized with D. pastinaca by some. The present study, using morphological comparisons and genetic analyses, demonstrates that there is a closely related species to D. past...

Tuna fisheries have been identified as one of the major threats to populations of other marine vertebrates, including sea turtles, sharks, seabirds and marine mammals. The development of technical mitigation measures (MM) in fisheries is part of the code of conduct for responsible fisheries. An in-depth analysis of the available literature regardin...

A new species of panray, Zanabatus maculatus sp. nov., is described from 12 type specimens collected in the Gulf of Guinea (Eastern Central Atlantic). The new species is distinguished from its sympatric congener, the striped panray Zanobatus schoenleinii , by its smaller size, heavier thorn pattern, spearhead-shaped dermal denticles and maculate co...

An investigation of combined CO1 and NADH2 data for rajid skates referable to Raja miraletus provided evidence that populations ranging from southern Africa to the North-East Atlantic and Mediterranean Sea, once considered to represent a cline, belong to a species complex consisting of at least four valid species. Raja miraletus appears to be confi...

A single specimen of a new Bathyraja skate was collected by the authors in 2003 during a survey of the deepwater biota of the northern Tasman Sea by the New Zealand FRV Tangaroa. This skate, labelled the 'blonde skate' by voyage participants, is uniformly white on all surfaces of the body and the skin is partly translucent. It belongs to a subgroup...

A new guitarfish, Rhinobatos borneensis sp. nov., is described from material collected at fish markets in Malaysian Borneo (South China Sea). This ray, which is almost plain coloured with faint orange blotches in adults, has a more colourful embryo marked with small pale ocelli with dark centres. Confused with R. Schlegelii (Japan to Taiwan) and it...
Article
Based on new photographs of the wound, Tirard et al. (2015) tried to demonstrate that the shark involved in a fatal attack on a human in Lifou in 2007 had homodont teeth and that it sawed the femur instead of directly cutting it, promoting the hypothesis that it was a tiger shark instead of a white shark. They also contested the data provided by th...

The bluespotted maskray, Neotrygon kuhlii (Muller & Henle, 1841), once thought to be widely distributed in the Indo-West Pacific, consists of a complex of several species and the type series consists of multiple species; its nomenclature is discussed. A lectotype and paralectotype are designated and the species rediagnosed based on the types and a...

During two surveys in 2011 and 2013, we deployed pop-up satellite archival tags (PSATs) on subadult or adult porbeagles at the Bay of Biscay shelf break. We collected data that enabled the reconstruction of nine migrations (eight females, one male) that uncover the large spatial extent of these sharks in the Northeast Atlantic. The mean duration of...

Recently, declining populations of several pelagic shark species have led to global conservation concerns surrounding this group. As a result, a series of species-specific banning measures have been implemented by Regional Fishery Management Organizations (RFMOs) in charge of tuna fisheries, which include retention bans, finning bans and trading ba...

Human impact on the oceans predates scientific observation, which for many animal populations has captured only recent changes. Such a limited knowledge can hamper finding optimal management and conservation strategies including setting appropriate recovery targets. Sawfishes are among the most endangered marine vertebrates in the ocean. Historical...

Several occurrences of White Sharks in tropical waters have been reported, but in the context of gaps in the knowledge of the ecology of that top predator, they appear as unusual and unexpected destinations. The New Caledonian exclusive economic zone covers 1,400,000 km 2 , with sea-surface temperatures oscillating between 20 and 21°C in winter and...
