Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Designing and evaluating alternative livelihoods for shark conservation: a case study on thresher sharks in Alor Island, Indonesia

Oryx
The pelagic thresher shark Alopias pelagicus is an Evolutionarily Distinct and Globally Endangered species primarily threatened by overfishing. Indonesia is the world's largest shark fishing nation, and in Alor Island, thresher sharks have been a primary

Evaluating species at risk in data‐limited fisheries: A productivity–susceptibility analysis for marine aquarium fish

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract The marine aquarium trade (MAT) is a significant global industry harvesting millions of wild‐caught, live coral reef fishes for public and private aquaria markets in the United States and Europe annually, while supporting fisher livelihoods in the Indo‐Pacific.

Isotopic trajectories and interspecific niche partitioning in tropical pelagic sharks

Global Ecology and Conservation
Pelagic sharks are top predators with key role in the structure and functioning of ocean ecosystems. However, little is known on their assemblage-wide trophic ecology.

High resolution data reveal fundamental steps and turns in animal movements

Ecological Monographs, Volume 96, Issue 2, May 2026.
Abstract Animal movement paths display substantial complexity and variability, promoting efforts to identify universal rules and models that best describe them. Using high‐resolution (≥10 Hz) movement from 43 vertebrate species spanning diverse taxa, body sizes, and lifestyles, we show that paths are universally composed of straight‐line steps ...

Potential Hierarchical Interactions of Megafauna Species at a Cleaning Station

Fishes
Cleaning stations on seamounts play a crucial ecological role in the health and behavior of marine megafauna, yet interspecific interactions at these sites remain understudied.

Mitigating catches of endangered sharks species in small-scale fisheries: a case study on pelagic thresher sharks (Alopias pelagicus Nakamura, 1935) in the eastern Indian Ocean

, 2022
Many shark species (Class Chondrichthyes) are threatened with extinction due to overfishing. Of the >1,000 described Chondrichthyan species, the pelagic thresher sharks (Alopias pelagicus) are of particular conservation priority since they are evolutionarily distinct and globally endangered.
