Ridges and riblets: Shark skin surfaces versus biomimetic models
Ridges and riblets: Shark skin surfaces versus biomimetic models Molly K. Gabler-Smith, George V. Lauder ABSTRACT: Shark skin has been an inspiration for biomimetic materials and structures due to its role in reducing drag and enhancing thrust, properties believed to be due to the textured surface composed of ridges on the surface of individual tooth-like
Biomechanics of the jaws of spotted ratfish
Biomechanics of the jaws of spotted ratfish Amanda M. Herbert, Mason N. Dean, Adam P. Summers, Cheryl D. Wilga ABSTRACT: Elasmobranch fishes (sharks, skates and rays) consume prey of a variety of sizes and properties, and the feeding mechanism typically reflects diet. Spotted ratfish, Hydrolagus colliei (Holocephali, sister group of elasmobranchs), consume both hard and

Coffey, Adrian C. Gleiss, Charlie Huveneers, David J. Curnic, et al. ABSTRACT: Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and
Increased shark bite survivability revealed by two centuries of Australian records
Increased shark bite survivability revealed by two centuries of Australian records Jason P. Tucker, Isaac R. Santos, Brendan P. Kelaher, Marcel Green, Graeme F. Clark, Paul A. Butcher ABSTRACT: The perceived and real threat of shark bites have significant direct health and indirect economic impacts. Here we assess the changing odds of surviving an unprovoked

Fisher–shark interactions: A loss of support for the Maldives shark sanctuary from reef fishers whose livelihoods are affected by shark depredation Danielle Robinson, Steven P. Newman, Mark J. Whittingham, Richard M. Francksen, M. Shiham Adam, Selina M. Stead ABSTRACT: Targets for protecting predatory species often fail to consider the human costs of conservation. Human–wildlife interactions
