The shark tore off his arm and then swam away. “It’s at the bow going down the port side,” calls Warrick Lyon, a NIWA scientist. “You don’t have to spend long at the South Sea Hotel to hear stories about great whites,” says Storm Stanley, who’s been paua diving on Stewart Island for years and is now chairman of the Paua Industry Council. They’ve been named, measured and photographically identified—Ella, Phred, Miranda, Chopper, Barney—namesakes of children, friends and family of the crew. The waters of Edwards Island close over the top, fizzing with spume.

It was a single moment of clarity in the thrashing white water. Subscribe to our free newsletter for news and prizes. In their emergency plan, anyone injured on Campbell Island is to evacuated by helicopter more than 450 miles to the nearest hospital. But it is persistent reports of very large and very small sharks around the beaches of Northland that make Duffy most curious. With the crack of a bull whip, the line is sheared off and ricochets back into the boat. Wroe’s model cannot account for the unique hunting behaviours of great whites: colliding with their prey, mouths open, at speeds that send the one-tonne animals flying into the air, and the shaking from side to side to tear sea lions in half in less than a second. SHARK ATTACK MAP 2018 – 2019. He pulls up his shirt sleeves, easing aside the plastic prosthetic to display a myriad of 10 cm long scars that still cover each arm. Stephen Wroe of the University of New South Wales in Sydney has used sophisticated mathematical modelling to predict the maximum bite force of great whites and their extinct cousins, the megalodons. Since the incident, Mike and Linda have grown closer to each other. In part, this is due to the peculiar anatomy of the great white that allows it to exist in regions where few other sharks can survive. Deliberately attracting sharks with chum then putting divers in the water modifies their behaviour. As Wynn helped refuel the helicopter in mid-air, it was in range on Campbell Island, but there was a heavy cloud cover in the area. Every year, pilot whales beach on the sandy shores of the Chatham Islands. There a case of good luck, good planning, and just everything came off. As it slides along the port side, skipper “Barney” Brown calls the tail at the transom and Duffy lines up the snout with measurements scribed on the gunwale of the Jester—at least 4.1 m long, and probably approaching a tonne. But Duffy’s taking a punt on this last shark to reveal a more complete pattern of migration. Then the call goes up, “Shark on!”. But here’s the juicy bit. Please create one below, or sign in if you already have one. Campbell Island is located about 700km south of the New Zealand mainland, and is a sub Antarctic island. All that remains are the swirling vortices of where the beast has been; the power, the fury, slips silently into the deep channel with the shark.

At the end is an inch-long stainless-steel spike and a pop-up archival transmitting (PAT) tag that will track the location of the shark every few seconds for the next 11 months—invaluable data for understanding the animals. Like a train hitting a bicycle, the force of the impact drove him deep underwater and knocked the mask from his face. In fact, he didn’t even see it coming. Conversely, the most imposing dental architecture belongs to animals that are long extinct. But I'm just extremely grateful to everyone involved," he stated. DOC’s Phred Dobbins hauls in the throw baits hanging from the transom—they’re there to entice the sharks, not to be eaten. It now seems possible that a great white could inhabit water as cold as 7ºC. Once they stabilized Mike within 3 hours, they loaded him in the helicopter within sunrise as all his friends looked on, exhausted and worried. Knowing that they were medically ill-equipped to cope with Mike's injury, Robin pulled a strap from his mask and put it over Mike's right arm to use as a tourniquet to contain the blood loss.

Great whites and lions are both listed as threatened, whereas humans, with a meagre bite force of 80 kg, have multiplied like a virus. But he didn't know that a great white shark was coming at him. “You’ve suddenly got a predator-prey thing going on,” says Stanley. The largest shark approaches the port side, Duffy ominously following its form with a long prod. Gerard Hutching, 'Sharks and rays - Shark attacks', Te Ara - the Encyclopedia of New Zealand, http://www.TeAra.govt.nz/en/photograph/5339/subantarctic-shark-attack (accessed 1 October 2020), Story by Gerard Hutching, published 12 Jun 2006. “I can’t understand why people want to kill apex predators,” he says. The jaws of his assailant had closed firmly over both arms, sinking its teeth through the neoprene wetsuit and into the bone. However, mammals and birds are endothermic (warm-blooded), equipped with a revolutionary anatomical system to regulate our own internal temperature—an elaborate trick that has enabled us to extend our range across an enormous variety of habitats. Jekyll had become Hyde, the monster had emerged and revealed its most monstrous tendencies. Possible, but also very expensive. And the pay-off is enormous. Two years later, Mike has adjusted to the loss of his right arm and he slowly continues to regain the use of his left one with physical therapy. Ask your librarian to subscribe to this service next year. It was an emphatic demonstration of power, and the illusion of grace we witnessed earlier is replaced instead with a profound sense of dread. Seals, sea lions…whales. Then suddenly, numbing relief.

So if Fraser wasn’t really a la carte, then what was? Fraser and his friends spent 20 minutes investigating the rocks and crevices of the bay and examining the sandy bottom that shelved gradually out to sea. … It had a mouthful of my arm and had a feed. This far south, sharks were the furthest thing from his mind—it was believed at the time that great whites never inhabited water less than 10ºC. "Mike and I have become an item. But as far as anyone can tell, apex predators like great white sharks have little structuring effect—their numbers are not large, they take few prey, and have no natural predators—with the exception of very rare territorial attacks by orcas or larger great whites. Eyes rolled back in blind fury. Rumours that a mainlander has started a cage-diving operation for tourists, chumming the same water as the local divers extract their livelihood from, have turned out to be true.

The water temperature can get very low, rarely above 9 degrees in the summer, (and around 7 degrees in April) and the average year round temperature on land is 6 degrees. How often do they breed? Yet despite their reputation as maneaters, great whites are protected in New Zealand as a vulnerable species. "You're talking about a 36-hour boat trip to get him off the island. So far the team have tracked great whites from Stewart Island to Australia, and from the Chathams to Tonga. He looked back to see his four colleagues enter the water, and together they swam through kelp that swayed rhythmically in the Southern Ocean surge like twisted ribbons in the wind.

Due to the remote location of the beaches, this behaviour has never been observed, here or anywhere else on Earth. He now has two prosthetic arms, one for lighter work such as computer work and the other one used for heavy duty, like trimming down trees and such. “I’ve seen plenty of dead whales,” says Clinton Duffy, “and those bites were very fresh.” The night of the stranding, there was a three- to four-metre sea running and it seems that the great whites were actually devouring the stranded whales in the shallows, between the surf line and the beach. But we also revere them as charismatic mega-fauna, and as killing machines—one of the few predators that continue to take human lives.

* We’ll never pass your email address to third parties, or send you spammy stuff, we promise. It seems likely, for instance, that the great whites that Duffy has tagged at the Chatham Islands time their winter tropical holiday to coincide with humpback whale migration— specifically, the times and locations humpbacks are known to calve. An extra sense allows them to “hear” electrical signals as low as five billionths of a volt per centimetre—the equivalent of electrodes connected to a flashlight battery 16,000 km apart in the ocean—opening a sensory realm of electrical fields that we cannot begin to imagine. However, he and a team of scientists are piecing together clues from international research and chance observations by fishermen and sifting through an astonishing volume of data he collects from satellite tags that offers some of the best clues to their enigmatic movements, and their continued survival. It is the responsibility of the user of any material to obtain clearance from the copyright holder. Particularly encouraging, Duffy has identified two sharks seen at Stewart Island last year, adding to a growing body of observational evidence that these sharks are creatures of habit, returning year after year to favoured feeding grounds.
