SOUTHAMPTON, N.Y. (AP) \u2014 Just off one of New York\u2019s famed Hamptons beaches, shark researcher Greg Metzger reels in one of the day\u2019s prize catches: a young but powerful sand tiger shark.<\/p>\n
He and another marine researcher quickly lasso the tail of the sharp-toothed female to the side of the boat and hold it steady as they take tissue samples and work to attach small data collection devices. Metzger marvels as the shark\u2019s thick, rugged skin snaps a surgical-grade scalpel.<\/p>\n
\u201cIt\u2019s no surprise that they\u2019ve been around since prehistoric times and they\u2019re still going strong,\u201d Metzger says as he stitches up the incision and sends it along its way.<\/p>\n
Metzger and other researchers are catching, tagging and releasing a wide range of sharks as they seek to understand the local population and shed more light on one of the world\u2019s few confirmed great white shark nurseries<\/a>, where masses of young predators spend their first vulnerable years feeding and growing. Other white shark nurseries recognized globally are in the coastal waters off California, Mexico and Australia.<\/p>\n \u201cIt\u2019s that initial fear of sharks that captures people\u2019s imagination,\u201d said Metzger, who also teaches marine science at Southampton High School. \u201cHopefully, through educational opportunities like today, we\u2019ll be able to show that these sharks are far from mindless eating machines.\u201d<\/p>\n <\/p>\n \n AP AUDIO: Researchers catch sharks off NY\u2019s Hamptons, attach trackers to toothy predators\n <\/p>\n AP correspondent Julie Walker reports on sharks in the Hamptons, fictional home to the original Jaws.<\/p>\n Warmer waters are drawing tropical sharks north<\/p>\n The researchers attach different types of tags. One relays location by sending an acoustic signal that can be detected by monitoring receivers set up along the coast. Another measures depth and water temperature for several months, then pops off. <\/p>\n The data illustrates how sharks can cover vast distances in a year, said Bradley Peterson, the Stony Brook University marine scientist working with Metzger this particular day.<\/p>\n \u201cTheir tags are being detected in North Carolina and Georgia and Florida and the Gulf of Mexico, and then they\u2019ll be back here the following year,\u201d he said. \u201cSo a lot of them are coming up here to get themselves fueled up and fattened up.\u201d<\/p>\n The research also suggests more varied species of sharks are coming up from more tropical southern waters during the summer months, as the waters off Long Island\u2019s coast and elsewhere are warming, likely due to climate change, said Frank Quevedo, executive director at the South Fork Natural History Museum and Nature Center, which is coordinating the research.<\/p>\n \u201cWe\u2019re seeing more spinner sharks, more black tip sharks, more bull sharks,\u201d he said as he showed off the Bridgehampton museum\u2019s interactive exhibit on the work. \u201cThese are temperate sharks that utilize this habitat when the food source is here. So right now is like prime time.\u201d<\/p>\n <\/p>\n \n Sign up for Morning Wire:<\/strong> To be clear, the waters off Long Island have long been known to be a haven for all manner of sharks. The bestselling Peter Benchley novel \u201cJaws\u201d was set in a fictional seaside town in the Hamptons before the blockbuster film version, which Netflix is bringing back to its streaming library Tuesday along with its sequels, was shot on location on Martha\u2019s Vineyard, Massachusetts.<\/p>\n The International Shark Attack File, a database at the Florida Museum of Natural History, includes no records of a fatal shark attack on Long Island, though beachgoers have been bitten in recent years, including one this summer<\/a>, prompting local officials to invest in safety measures, including shark-spotting drones<\/a>.<\/p>\n \u201cThere\u2019s this huge misconception that there\u2019s this surge of sharks in Long Island waters. These sharks have always been here,\u201d Metzger said. \u201cA reason why we\u2019re seeing more is because of technology. There\u2019s more drones. Everybody\u2019s got a cellphone now.\u201d<\/p>\n Researchers are learning more about baby whites<\/p>\n Quevedo says baby whites are already about 4 feet (1.2 meters) long and weigh up to 80 pounds (36 kilograms) at birth, and they aren\u2019t reared by their mothers, meaning they must immediately fend for themselves.<\/p>\n That\u2019s why they\u2019re drawn to the relatively shallow, coastal areas off Long Island, where they can safely feed on schools of fish away from other predators, including older sharks, he said.<\/p>\n \u201cIt\u2019s just like in nursery school, where kids learn the basics,\u201d Quevedo explained.<\/p>\n
