Blue Sharks Use Eddies for Fast Track to Food

News Release Woods Hole Oceanographic Institution 07. August 2019 — — — — — — — — — — — Blue sharks use large, swirling ocean currents, known as eddies, to fast-track their way down to feed in the ocean twilight zone—a layer of the ocean between 200 and 1000 meters deep containing the largest

Mesoscale eddies release pelagic sharks from thermal constraints

Mesoscale eddies release pelagic sharks from thermal constraints to foraging in the ocean twilight zone Camrin D. Braun, Peter Gaube, Tane H. Sinclair-Taylor, Gregory B. Skomal, and Simon R. Thorrold ABSTRACT: Mesoscale eddies are critical components of the ocean’s “internal weather” system. Mixing and stirring by eddies exerts significant control on biogeochemical fluxes in the

Reproductive biology, multiple paternity and polyandry of the bull shark Carcharhinus leucas Agathe Pirog, Hélène Magalon, Thomas Poirout, Sébastien Jaquemet ABSTRACT: To improve understanding of bull shark Carcharhinus leucas reproductive biology, we analysed reproductive traits from 118 bull sharks caught along Reunion Island coasts (Western Indian Ocean), including 16 gravid females. Specific microsatellite loci were
