Abstract One third of chondrichthyan species (sharks, rays, and chimeras) are threatened with extinction, mainly due to unsustainable fishing. Large accessible international markets for meat and luxury products like dried fins can help drive overfishing by encouraging targeted capture or retention of high‐value export species.

Spatially explicit risk assessment of marine megafauna vulnerability to Indian Ocean tuna fisheries
Abstract By‐catch is the most significant direct threat marine megafauna face at the global scale. However, the magnitude and spatial patterns of megafauna by‐catch are still poorly understood, especially in regions with very limited monitoring and expanding fisheries.

Abstract Increasing fishing pressure has negatively impacted elasmobranch populations globally. Despite high levels of historical and current fishing pressure, the Bay of Bengal region remains data‐poor. Focusing on Bangladesh, we conducted a socio‐ecological study to characterize elasmobranch fisheries and evaluate their impact on threatened species ...

Abstract The capture of a female specimen of the velvet belly lantern shark Etmopterus spinax with abnormal skin coloration is reported. The specimen was captured off northern Spain (Bay of Biscay, North‐eastern Atlantic) in 2021 by bottom trawling. The lack of dermal melanophores combined with a normal retinal pigmentation, lead us to considerate the ...

Offshore platforms as novel ecosystems: A case study from Australia’s Northwest Shelf
We assessed the marine communities at the Wandoo offshore oil platform in northwest Australia, and compared these communities with natural habitats. We found that the marine community at Wandoo more closely resembles that of a natural reef than the community that would have been present prior to the installation of the platform. The Wandoo platform can

Drivers of reef fish assemblages in an upwelling region from the Eastern Tropical Pacific Ocean
Abstract Reef fish assemblages are exposed to a wide range of anthropogenic threats as well as chronic natural disturbances. In upwelling regions, for example, there is a seasonal influx of cool nutrient‐rich waters that may shape the structure and composition of reef fish assemblages.

First record of a single-clasper specimen of Pseudobatos percellens (Elasmobranchii: Rhinopristiformes: Rhinobatidae) from the Caribbean Sea, Venezuela [PDF]
Documented cases of abnormalities in elasmobranchs worldwide are more often reported for sharks than their close relatives, the skates and rays. This report confirms the occurrence of a chola guitarfish, Pseudobatos percellens (Walbaum, 1792), caught off

A Neoselachian shark from the non-marine Wessex Formation (Wealden Group: early Cretaceous, Barremian) of the Isle of Wight, southern England [PDF]
Bulk screening of Early Cretaceous (Barremian) Wessex Formation strata exposed on the south-east coast of the Isle of Wight, southern England, has resulted in the recovery of neoselachian shark teeth referred to the scyliorhinid Palaeoscyllium. These are
