** FILE ** A great white shark breaches the water in False Bay, Cape Town, South Africa, in this undated file photo. A shark of the same species attacked and presumably killed an elderly woman, Tyna Webb, as she swam Monday Nov. 15, 2004 off Sunny Cove in Fish Hoek as she had for 17 years. About 15 people witnessed the attack and she was presumed dead, officials said.
