The complete mitogenome of the Critically Endangered smalltooth sand tiger shark

The complete mitogenome of the Critically Endangered smalltooth sand tiger shark, Odontaspis ferox (Lamniformes: Odontaspididae) Noel Vella, Adriana Vella ABSTRACT: Here, we report the first complete mitochondrial genome for the smalltooth sand tiger shark, Odontaspis ferox (Risso, 1810). The circular mitochondrial genome was found to be 16,682 bp in length and contains 37 genes, a control

Body dimensions of the extinct giant shark Otodus megalodon

Body dimensions of the extinct giant shark Otodus megalodon

Body dimensions of the extinct giant shark Otodus megalodon: a 2D reconstruction Cooper J.A., Pimiento C., Ferrón H.G., Benton M.J. ABSTRACT: Inferring the size of extinct animals is fraught with danger, especially when they were much larger than their modern relatives. Such extrapolations are particularly risky when allometry is present. The extinct giant shark †Otodus megalodon

Urban manta rays

Urban manta rays: potential manta ray nursery habitat along a highly developed Florida coastline Jessica H. Pate, Andrea D. Marshall ABSTRACT: The giant oceanic manta ray Mobula birostris was listed in the US Endangered Species Act as a threatened species in 2018, yet insufficient data exist on manta populations throughout US waters to designate critical

A hydrodynamics assessment of the hammerhead shark cephalofoil

A hydrodynamics assessment of the hammerhead shark cephalofoil

A hydrodynamics assessment of the hammerhead shark cephalofoil Matthew K. Gaylord, Eric L. Blades, Glenn R. Parsons ABSTRACT: Hammerhead sharks are characterized by a conspicuous lateral expansion of the head forming a structure known as a cephalofoil. Two theories regarding the function of this structure suggest that it may increase maneuverability as well as produce

Seasonal Movements and Habitat Use of Juvenile Smooth Hammerhead Sharks in the Western North Atlantic Ocean

Seasonal Movements and Habitat Use of Juvenile Smooth Hammerhead Sharks in the Western North Atlantic Ocean and Significance for Management Ryan K. Logan, Jeremy J. Vaudo, Lara L. Sousa, Mark Sampson, Bradley M. Wetherbee, Mahmood S. Shivji ABSTRACT: Upper trophic level predators dramatically impacted by fisheries include the large-bodied hammerhead sharks, which have become species

Social media: a valuable tool to inform shark conservation in Greece

Social media: a valuable tool to inform shark conservation in Greece

Social media: a valuable tool to inform shark conservation in Greece Taklis C., Giovos I., Karamanlidis A. ABSTRACT: Sharks in the Mediterranean Sea are facing an elevated risk of extinction; several species are considered endangered and some have been reduced to such low population numbers that they are hard to detect through conventional monitoring methods.

Shark discards in selective and mixed-species pelagic longline fisheries

Shark discards in selective and mixed-species pelagic longline fisheries

Shark discards in selective and mixed-species pelagic longline fisheries Gareth L. Jordaan, Jorge Santos, Johan C. Groeneveld ABSTRACT: The conservation status of several pelagic shark species is considered vulnerable with declining populations, yet data on shark fishing mortality remain limited for large ocean regions. Pelagic sharks are increasingly retained by mixed-species fisheries, or are discarded

Demographic and Exploitation Parameters of the Blue Shark in the Gulf of Guinea

Demographic and Exploitation Parameters of the Blue Shark, Prionace Glauca in the Gulf of Guinea (Togo-Benin-Nigeria) Calèbe Midinoudéwa, H.E.; Sohou, Z.; Tulashie, S.K.; Fiogbé, E.D. ABSTRACT: Prionace glauca, blue shark is a cosmopolitan species. Together with Carcharhinus falciformis, it co-dominated the landings of carcharhinidae sharks at the Artisanal Fishing Port of Cotonou. The objective of

Preliminary age and growth of the goblin shark

Preliminary age and growth of the deep-water goblin shark Mitsukurina owstoni (Jordan, 1898) Fabio P. Caltabellotta, Zachary A. Siders, Gregor M. Cailliet, Fabio S. Motta, Otto B. F. Gadig ABSTRACT: Owing to poorly mineralising structures, ageing deep-water elasmobranchs requires unconventional techniques. The aim of the present study was to develop an ageing method for the

Can drifting objects drive the movements of a vulnerable pelagic shark?

Can drifting objects drive the movements of a vulnerable pelagic shark? Lucas Bonnin, Christophe Lett, Laurent Dagorn, John David Filmalter, Fabien Forget, Philippe Verley, Manuela Capello ABSTRACT: Juvenile silky sharks (Carcharhinus falciformis) regularly associate with floating objects yet the reasons driving this behaviour remain uncertain. Understanding the proportion of time that silky sharks spend associated
