RedFox, they have shark cages which are sometimes used to ward off underwater predators.
A woman named Lynne Cox used a cage for her recent one-mile swim to Antarctica in thirty-two-degree water without a wet suit. She has also done the following:
* At age fourteen, she swam twenty-six miles from Catalina Island to the California mainland.
* At ages fifteen and sixteen, she broke the men's and women's world records for swimming the English Channel; a thirty-three-mile crossing in nine hours, thirty-six minutes.
* At eighteen, she swam the twenty-mile Cook Strait between North and South Islands of New Zealand, was caught on a massive swell, found herself after five hours farther from the finish than when she started, and still completed the swim.
* She was the first to swim the Strait of Magellan, the most treacherous three-mile stretch of water in the world.
* The first to swim the Bering Strait (the channel that forms the boundary line between the United States and Russia) from Alaska to Siberia, thereby opening the U.S.-Soviet border for the first time in forty-eight years, swimming in thirty-eight-degree water in four-foot waves without a shark cage, wet suit, or lanolin grease.
* The first to swim the Cape of Good Hope (a shark emerged from the kelp, its jaws wide open, and was shot as it headed straight for her).
