The Great White Shark is not endangered in the Eastern North Pacific, and, in fact, is doing well enough that its numbers likely are growing, according to an international research team led by a University of Florida researcher.
Speculation that a great white shark that went missing off Australia may have been devoured by another great white is making the Internet rounds this week, raising the question of whether it was an instance of shark cannibalism.
Her name is Katharine and she's 14 feet long and weighs more than a ton. She's been causing a bit of stir on Florida's east coast with a sighting off Key Largo on May 19 after she swam past Fort Lauderdale and Miami.
Comparing the antibodies of sharks, which are very old from an evolutionary perspective, with those of humans, a team of researchers at the Technische Universitaet Muenchen (TUM) and the Helmholtz Zentrum Muenchen discovered stabilizing mechanisms that can also be applied to optimize custom-tailored antibodies in humans.
Commercial fisher Carl Moore wasn’t sure what he had netted last week just south of Key West, Florida (map), when he saw the fish’s flat, blade-like snout. Only after the Georgia angler photographed and released his catch was its identity confirmed: It was a goblin shark, a rare deep-sea shark, and it’s believed to be only the second such specimen ever caught in the Gulf of Mexico.
Citizen Scientists Match Research Tool When Counting Sharks: Dive Guides Monitoring Sharks on Coral Reef at Similar Level to Telemetry
Shark data collected by citizen scientists may be as reliable as data collected using automated tools, according to results published April 23, 2014, in the open access journal PLOS ONE by Gabriel Vianna from The University of Western Australia and colleagues.
Instruments strapped onto and ingested by sharks are revealing novel insights into how one of the most feared and least understood ocean predators swims, eats and lives.
More than 750 sharks, tarpon, tuna and billfish, fitted with satellite-linked tags, are providing scientists with data on temperature and salinity at various depths in the Atlantic, Gulf and Caribbean.
There are more than a thousand species of sharks and rays in the world, and nearly a quarter of them are threatened with extinction
Greg Skomal clambered onto the hydraulic lift of a modified 126-foot Bering Sea crab fishing boat off of Cape Cod, staring at the object of his life’s devotion: 3,500 pounds of writhing, gunmetal gray muscle, shimmering under the ship’s spotlights.
A new study by scientists from Nova Southeastern University's (NSU) Save Our Seas Shark Research Centre and Cornell University published in final form today in the journal BMC Genomics now undertakes the first large-scale exploration of the great white shark's genetic repertoire
New research shows that great white sharks power their non-stop journeys of more than 2,500 miles with energy stored as fat and oil in their massive livers.
This summer, a new underwater robot will start tracking some of the ocean's top predators -- including great white sharks -- to learn more about their habits.
When a shark is spotted in the ocean, humans and marine animals alike usually flee. But not the remora -- this fish will instead swim right up to a shark and attach itself to the predator using a suction disk located on the top of its head.
As the nations of the world prepare to vote on measures to restrict international trade in endangered sharks in early March, a team of researchers has found that one of these species -- the oceanic whitetip shark -- regularly crosses international boundaries.
Conservationists failed to win new protections for threatened sharks in the Atlantic Ocean at the annual meeting of a major international fisheries commission, but they hope to make significant progress over the next few years.
Real-time information about the movement of basking sharks swimming off the coast of Scotland is now available online, thanks to a partnership between Scottish Natural Heritage and the University of Exeter.
Australia has created the world's largest network of marine reserves and will restrict fishing as well as oil and gas exploration in a major step to safeguard the environment and access to food.
The discovery of a new species of hammerhead shark may sound like bad news for swimmers. But shark bites are rare, and it turns out this may be worse news for sharks.
Streamlined sharks are legendary for their effortless swimming. George Lauder from Harvard University explains that the fish have long inspired human engineers, but more recently attention has focused on how the fish's remarkable skin boosts swimming.
A Murdoch University PhD student will spend a year living among Indonesian shark fishermen to investigate their impact on shark populations and the effects of conservation efforts on fishing communities.
Do you know what is indisputably awesome, even for those language-sticklers who claim you can only use awesome "in its original sense"? Great white sharks jumping out of the water to eat seals.
Four new sharks—including a "rapier wielding" sawshark—are among 140 new species discovered by California Academy of Sciences researchers in 2011, the institution announced in December.
The decline of large predators and other "apex consumers" at the top of the food chain has disrupted ecosystems all over the planet, according to a review of recent findings conducted by an international team of scientists and published in the July 15 issue of Science.
Rare fish use saw as "antenna" to detect electric fields of prey. They may not see dead people, but sawfish use a sixth sense based in their snouts to hunt and dismember prey, new research shows for the first time
Sharks are unable to distinguish colors, even though their close relatives rays and chimaeras have some color vision, according to new research by Dr. Nathan Scott Hart and colleagues from the University of Western Australia and the University of Queensland in Australia.
New research from the University of South Florida suggests that one of the evolutionary secrets of the shark's success hides in one of its tiniest traits
Going to sea then was chancier than going into outer space today, so a mariner’s life was rife with superstitions. Some superstitions may have had a tenuous basis in fact, but most were contrived beliefs and rituals that sailors relied upon to give them a feeling that, to some small extent, they had some control [...]

We can send a man to the moon, but the ocean is still a dark and mysterious place to researchers and scientists.
Everyone knows that sharks have an amazing sense of smell. Toss a chunk of salmon into the shark tank at the Monterey Bay Aquarium in California, and you can see it in action.
