For a multitude of reasons, great white sharks should be considered nature's ocean-dwelling superheroes — they're big and strong, live long lives, can heal their wounds remarkably fast, and it's even likely that they rarely get cancer. But how is it possible that these ancient giants have so many superhero-like traits? Scientists have now taken a major step toward answering that question by decoding the entire genome of the great white shark. An international team of researchers led by scientists at the Save Our Seas Foundation Shark Research Center and the Guy Harvey Research Institute at Nova Southeastern University in Florida sequenced the genome of the great white shark (Carcharodon carcharias) and compared it with the genomes of several other vertebrate species. The team discovered a wealth of unusual genetic characteristics that might explain why white sharks are the superheroes (or supervillains, if you're a plump sea lion) of the sea. Their study was published online on … [Read more...] about Here’s Why Great White Sharks Are Natural-Born Superheroes

The 42-year-old mother of two from Phoenix, Md., has her other eye on the near distance, on the sparkling Atlantic, where seals dance delightfully and invite something more menacing: the great white sharks that like to eat them.“It’s something we think about and we talk about,’’ Hosford said, squinting into a late-summer sun. “We talk about safety. But we’ve been coming here for seven years and that’s probably not going to change. It’s our family tradition.’’ Advertisement Related: State biologist ‘confident’ great white shark was responsible for Truro attackOn the … [Read more...] about ‘There have always been great whites down here, just not this close to the shore’
BLUE Sharks are ocean going predators that stalk the seas for prey and have been known to take a chunk out of the occasional human. But are they found in UK waters? Here's the lowdown on the sea beasts. Are blue sharks found in UK waters? Blue sharks can be found in British waters but they are only seasonal visitors. During the summer the beasts can appear in the seas around Britain as part of their highly migratory lifestyle. They can travel over 5,700 miles in a single trip. In the east Atlantic it is found from Norway to South Africa, including the Mediterranean. They are also found in the west Atlantic Ocean, the whole Pacific Ocean and the whole of the Indian Ocean. Brits don't need to fear going back into the water though as there has not been a documented unprovoked shark attack in British waters since 1847. Do blue sharks attack humans? Blue sharks have been known to attack humans but they could hardly be described as frequent "man-eaters". The predators, which have been … [Read more...] about Are blue sharks in UK waters, are they dangerous to people and how big do they get?
A heart-stopping video shared on Facebook by the Atlantic White Shark Conservancy shows a researcher's uncomfortably close encounter with a great white shark.In the clip, Dr. Greg Skomal, a marine fisheries biologist at the Martha's Vineyard Research Station, can be seen standing on the bow of a ship and searching for sharks off the coast of Wellfleet, Massachusetts. Suddenly, a great white shark breaches the surface of the calm water with mouth agape and lunges up towards Dr. Skomal, who then quickly retreats from his perch at the front of the vessel. "Holy crap! It jumped right out of the water," the boat's driver can be heard yelling in the background of the video. "Did you see that? Did you see that?" Dr. Skomal replies. "It came right out and opened his mouth right at my feet." 8 PHOTOS Atlantic White Shark Conservancy See Gallery Atlantic White Shark Conservancy While out on research trips, we've seen white sharks breach and we've … [Read more...] about Terrifying video shows great white shark leap out of water towards researcher
Tech & Science A great white shark startled a couple of fisherman off the coast of Australia on Sunday after the creature appeared to chase the men in their kayaks. At one point, one of the men, Ken Gerke, had to slap the water with his paddle to scare off the shark. A shaky video shows a dark fin quickly cutting through the water toward his boat. “It’s chasing me,” he says in a panicked voice on the video recording. "I can hear him coming. Like I'm paddling, and I can hear him thumping away behind me." “Holy s**t. That’s a big white,” he said to his friend, David Barwise.
