STEPHEN FRAZIER, CNN ANCHOR: As you recall, a number of shark attacks this summer have led some publications to call this "the Summer of the Shark." In Australia and South Africa and other places, they use nets to protect swimmers from sharks. Often, though, they snare dolphins, which then die because they can't get to the surface to breathe. Scientists in South Africa now say they have found a solution to that, a sound solution. Here's ITN's Penny Marshall with a report.</s>PENNY MARSHALL, ITN CORRESPONDENT (voice-over): Dawn of South Africa's east coast, and the team from the</s>DR. VIC PEDDEMORS, SCIENTIST: I'm hoping that we will save the dolphins</s>MARSHALL: In the last few years, protecting beaches with shark nets has caused enough dolphin casualties here to put one species, the humpback, onto the endangered list. (on camera): Until now, keeping these beaches shark-free has meant killing dolphins, but this technology has changed that. And if these pingers are applied to fishermen's nets out at sea, they could save hundreds of thousands of marine mammals worldwide. (voice-over): So, if South Africa's dolphins seem to swim in safer waters as a result of this invention, scientists are hoping the pinger will become mandatory on fishing vessels all over the world.
