Feeding ecology has shaped the evolution of modern sharks Mohamad Bazzi, Nicolás E. Campione, Benjamin P. Kear, Catalina Pimiento, Per E. Ahlberg SUMMARY: Sharks are iconic predators in today’s oceans, yet their modern diversity has ancient origins. In particular, present hypotheses suggest that a combination of mass extinction, global climate change, and competition has regulated

Whale shark rhodopsin adapted to its vertically wide-ranging lifestyle Kazuaki Yamaguchi, Mitsumasa Koyanagi, Keiichi Sato, Akihisa Terakita, Shigehiro Kuraku ABSTRACT: Spectral tuning of visual pigments often facilitates adaptation to new environments, and it is intriguing to study the visual ecology of pelagic sharks with expanded habitats. The whale shark, which dives into the deep sea

Demon Monsters or Misunderstood Casualties?

Demon Monsters or Misunderstood Casualties? Writing about Sharks in Australia Donna Lee Brien ABSTRACT: Over the past century, many books for general readers have styled sharks as “monsters of the deep” (Steele). In recent decades, however, at least some writers have also turned to representing how sharks are seriously threatened by human activities. At a

The sharks and rays of Palau

The sharks and rays of Palau: biological diversity, status, and social and cultural dimensions Katelyn Hari, Vanessa Jaiteh B, Andrew Chin ABSTRACT: Anthropogenic pressures have been increasing on shark and ray populations globally, and their conservation and management can be compromised by lack of information on their diversity and status of species. This study presents

Nanolatticed Architecture Mitigates Damage in Shark Egg Cases

Nanolatticed Architecture Mitigates Damage in Shark Egg Cases Rubayn Goh, Scott P. O. Danielsen, Eric Schaible, Robert M. McMeeking, J. Herbert Waite ABSTRACT: Structural versatility and multifunctionality of biological materials have resulted in countless bioinspired strategies seeking to emulate the properties of nature. The nanostructured egg case of swell sharks is one of the toughest

Microplastics in fecal samples of whale sharks

Microplastics in fecal samples of whale sharks

Microplastics in fecal samples of whale sharks (Rhincodon typus) and from surface water in the Philippines Yong, M.M.H., Leistenschneider, C., Miranda, J.A. et al. ABSTRACT: Marine plastic abundance has increased over the past 60 years and microplastics (< 5 mm) constitute a primary component of such litter. Filter-feeding megafauna, such as the whale shark, might be particularly affected

Portuguese Artisanal Fishers’ Knowledge About Elasmobranchs—A Case Study Priscila M. Silva, Célia M. Teixeira, Cristina Pita, Henrique N. Cabral, Susana França ABSTRACT: The high economic value of fisheries was historically associated to commercial teleost fishes. Since the 1970s, despite some elasmobranchs becoming an important target or a bycatch, relatively little research has been carried out
