Early gigantic lamniform marks the onset of mega-body size in modern shark evolution

Mohamad Bazzi, Mikael Siversson, Sabine P. Wintner, Michael G. Newbrey et autres

Lamniform sharks are amongst the largest-bodied extant fishes and have an evolutionary history spanning ~135 million years (Ma). Fossils correlate their initial development of mega-body size ( ≥ 6 m) with ecological radiation as marine top-predators during the later part of the …

Horizontal and vertical movements and habitat use of the common thresher shark Alopias vulpinus in the western North Atlantic

Jeff Kneebone, Martin C. Arostegui, Lisa J. Natanson, Gregory B. Skomal et autres

In the western North Atlantic (WNA), the common thresher shark Alopias vulpinus is captured by several fisheries, but its population status has not formally been assessed, and its ecology and population structure are poorly understood. A total of 61 pop-up satellite archival …

Mineralized tissue of shark vertebral centra studied with microCT under in situ load

Stuart R. Stock, J. Parker, Michelle S. Passerotti, Lisa J. Natanson et autres

Shark vertebral bodies (centra) possess remarkable resistance to millions of cycles of large in vivo strains exceeding 4 to 8%. These strains are enormous for a mineralized tissue, and it appears that the centra evolved to achieve this performance through a hierarchy …

First insights into the vertical habitat use of young porbeagles in the north-western Atlantic with implications for bycatch reduction strategies

Brooke N. Anderson, Heather D. Bowlby, Steven Saul, Yun Hee Kang et autres

Context For threatened marine species, data on their vertical habitat use patterns can reveal risk of interactions with fishing gear and can inform bycatch avoidance strategies. Such data are lacking for young porbeagles (Lamna nasus), which are captured as bycatch in north-western …

Energy-dispersive diffraction tomography of shark vertebral centra

Jun‐Sang Park, Ryan M. Horn, Haiyan Chen, Kelsey C. James et autres

Shark vertebrae and their centra (vertebral bodies) are high-performance structures able to survive millions of cycles of high amplitude strain despite lacking a repair mechanism for accumulating damage. Shark centra consist of mineralized cartilage, a biocomposite of bioapatite (bAp), and collagen, and …

Vertebral morphology in the tail-whipping common thresher shark, Alopias vulpinus

Jamie L. Knaub, Michelle S. Passerotti, Lisa J. Natanson, Tricia L. Meredith et autres

spp.) are characterized by an elongated, scythe-like caudal fin that is used in tail-whipping, a behaviour where the tail is thrown overhead to stun prey. Tail-whipping is performed via extreme dorsoventral bending of the vertebral column, and is dramatically different from lateral …
