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.
