First record of the cirripede Anelasma squalicola in the Mediterranean Sea

First record of the cirripede Anelasma squalicola Darwin, 1852 (Pollicipedidae) in the Mediterranean Sea ALBA MARTÍN-LÁZARO, WOLF ISBERT, AIGÜES REPULLÉS-ALBEDA, CRISTINA GARCÍA-RUIZ, FRANCISCO E. MONTERO ABSTRACT: Anelasma squalicola Darwin 1852, is a barnacle that occurs on elasmobranchs from the Atlantic, Pacific, Arctic and Indian Ocean. It infects sharks of the families Etmopteridae and Pentanchidae. The

Conservation successes and challenges for wide-ranging sharks and rays Nathan Pacoureau, John K. Carlson, Holly K. Kindsvater, Nicholas K. Dulvy ABSTRACT: Overfishing is the most significant threat facing sharks and rays. Given the growth in consumption of seafood, combined with the compounding effects of habitat loss, climate change, and pollution, there is a need to

Inferring habitat use of the Pacific White Shark using vertebral chemistry John A. Mohan, Alfonsina E. Romo-Curiel, Sharon Z. Herzka, R. J. David Wells, Nathan R. Miller, Oscar Sosa-Nishizaki, Emiliano García-Rodríguez ABSTRACT: The conservation and management of highly migratory sharks relies on understanding age-related movements and nursery habitat utilization. We reconstructed the habitat use and

Are shark teeth proxies for functional traits? A framework to infer ecology from the fossil record Jack A. Cooper, John N. Griffin, René Kindlimann, Catalina Pimiento ABSTRACT: Modern sharks have an evolutionary history of at least 250 million years and are known to play key roles in marine systems, from controlling prey populations to connecting

Global hotspots of shark interactions with industrial longline fisheries Echelle S. Burns, Darcy Bradley, Lennon R. Thomas ABSTRACT: Sharks are susceptible to industrial longline fishing due to their slow life histories and association with targeted tuna stocks. Identifying fished areas with high shark interaction risk is vital to protect threatened species. We harmonize shark catch

Teeth outside the mouth: The evolution and development of shark denticles Rory L. Cooper, Ella F. Nicklin, Liam J. Rasch, Gareth J. Fraser ABSTRACT: Vertebrate skin appendages are incredibly diverse. This diversity, which includes structures such as scales, feathers, and hair, likely evolved from a shared anatomical placode, suggesting broad conservation of the early development
