Great white sharks have been around for more than four million years, yet they remain one of the world's most mysterious animals. Scientists know that the beasts have special organs for sensing electromagnetic fields and that their jaws can snap down with 4,000 pounds of force. But migration patterns, which are critical for conservation efforts, are mostly unknown.
It's not known how far great whites—whose worldwide numbers are estimated to be fewer than 3,500—migrate or if there's a season when they spend more time near the coast, says Rory McAuley, a senior research scientist with Western Australia's Department of Fisheries. McAuley hopes that the buoys, along with about 50 sensors on the ocean floor, will also reveal behavior. This information could help authorities better predict the monthly risk at beaches and restrict seasonal shipping routes to protect sharks from boats.
As a bonus, the work could give swimmers a heads-up when a great white is closing in. If a tagged shark swims within approximately a quarter-mile of a coastal buoy, the system sends a text to lifeguards on nearby beaches. Even swimming at top speed, it might take the dangerous fish a couple of minutes to reach shore, possibly enough time for the lifeguards to drop the phone and sunscreen and get folks out of the water.
@ShermanShark: Yeah,eatn a tourist LOL
Some how I was offended by referring to Great Whites as "Man-eaters". I understand we are just more meat floating at the waters surface for them to attack, and if I was a Great White I would sure take my revenge out on man-kind with all those renewable resources that have at their disposal, aka teeth. Still, seems to make people believe they are "Man-Hunters" also, which I don't consider true.
Awesome Tech though, I could see this being used on plenty of different species on land and in water.
