(Phys.org) —A ground-breaking new study challenges popular assumptions about the feeding behaviour of the world's largest predatory fish, the white shark. http://phys.org/news282990252.html Biology Wed, 20 Mar 2013 09:24:36 EST news282990252 (Phys.org)—Researchers examining a fossil specimen discovered in a museum storage bin have found it to be the remains of a super-predator that lived during the Jurassic Period, around 165 million years ago. They describe the specimen, named Tyrannoneustes lythrodectikos, in their paper published in the Journal of Systematic Palaeontology, as looking like a cross between a modern dolphin and a shark or crocodile. http://phys.org/news278667323.html Other Sciences Tue, 29 Jan 2013 08:20:01 EST news278667323 In the marine world, high-energy prey make for high-energy predators. And to survive, such marine predators need to sustain the right kind of high-energy diet. Not just any prey will do, suggests a new study by researchers from the University of British Columbia and University of La Rochelle, in France. http://phys.org/news272739527.html Biology Wed, 21 Nov 2012 17:00:02 EST news272739527 Biologists have shown how an advanced set of teeth give Antarctic leopard seals the biological tools to feast on prey of all sizes, from penguins to tiny krill. http://phys.org/news270809743.html Biology Tue, 30 Oct 2012 09:55:56 EST news270809743 A few days ago, Stanford marine biologists were excited to detect a white shark swimming along the California coast north of San Francisco. Although the biologists routinely monitor sharks, this particular moment marked the first step toward a "wired ocean" full of mobile robotic receivers and moored listening stations that can detect ocean wildlife as it swims by. http://phys.org/news265020082.html Biology Fri, 24 Aug 2012 10:10:11 EST news265020082 An international study to understand and predict the likely impact of ocean acidification on shellfish and other marine organisms living in seas from the tropics to the poles is published this week (date) in the journal Global Change Biology. http://phys.org/news263387165.html Space & Earth Sun, 05 Aug 2012 19:00:01 EST news263387165 (Phys.org) -- Scientists are delving into the social networking behaviour of sharks, to determine why and when large marine predators congregate, and the mysteries of their society. http://phys.org/news262248097.html Biology Mon, 23 Jul 2012 08:10:03 EST news262248097 In arid southern Peru, geologists are fighting time and the elements to preserve a precious find: a vast whale cemetery dating back millions of years. http://phys.org/news261285131.html Other Sciences Thu, 12 Jul 2012 04:12:22 EST news261285131 Researchers at the University of California, Santa Cruz, who pioneered the use of satellite tags to monitor the migrations of elephant seals have compiled one of the largest datasets available for any marine mammal species, revealing their movements and diving behavior at sea in unprecedented detail. http://phys.org/news256309786.html Biology Tue, 15 May 2012 17:00:13 EST news256309786 Rolling from his surfboard, blood gushing from the wound where a shark had just ripped a big chunk of flesh from his thigh, Australian Glen Folkard had just one thought: "I'm alive." http://phys.org/news251694902.html Biology Fri, 23 Mar 2012 04:15:15 EST news251694902 Iconic marine predators such as sharks, tunas, swordfish, and marlins are becoming increasingly rare under current fishing trends, say University of British Columbia researchers. http://phys.org/news242323359.html Biology Mon, 05 Dec 2011 16:02:57 EST news242323359 Like the vast African plains, two huge expanses of the North Pacific Ocean are major corridors of life, attracting an array of marine predators in predictable seasonal patterns, according to final results from the Census of Marine Life Tagging of Pacific Predators (TOPP) project published in the June 23 edition of the journal Nature. http://phys.org/news228573374.html Biology Wed, 29 Jun 2011 13:36:49 EST news228573374 Paleontologists have discovered that a group of remarkable ancient sea creatures existed for much longer and grew to much larger sizes than previously thought, thanks to extraordinarily well-preserved fossils discovered in Morocco. http://phys.org/news225546916.html Other Sciences Wed, 25 May 2011 13:00:01 EST news225546916 (PhysOrg.com) -- The evolution of ichthyosaurs, important marine predators of the age of dinosaurs, was hit hard by a mass extinction event 200 million years ago, according to a new study from the University of Bristol published in PNAS. http://phys.org/news223712226.html Other Sciences Wed, 04 May 2011 08:30:01 EST news223712226
