ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Abstract Ecosystem dynamics can lead to trade‐offs between reaching harvest targets and protecting vulnerable species across fisheries management decisions. However, in the context of rebuilding overfished populations, considering predator–prey interactions might provide opportunities to minimize or reverse these trade‐offs if overfished prey can ...

Several reproductive specializations are found within the elasmobranchs. All elasmobranchs fertilize internally and produce a relatively small number of large eggs. Elasmobranch fecundity generally ranges from one to two offspring produced a year up to a

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.

Shark bite scars were analysed on coastal dolphins in southeast Queensland, Australia to compare the predation risk between species and habitats. Australian humpback dolphins (Sousa sahulensis) exhibited the highest bite rates and individuals found in sheltered waters had higher shark bite scar prevalence than open waters.
