Why Sharks Attack

Why Sharks Attack

In recent years, an unusual spate of deadly shark attacks has gripped Australia, resulting in five deaths in 10 months. At the same time, great white sharks have begun appearing in growing numbers off the beaches of Cape Cod, Massachusetts, not far from the waters where Steven Spielberg filmed the ultimate shark fright film, Jaws. What's behind the mysterious arrival of this apex predator in an area where they've rarely been seen for hundreds of years? Are deadly encounters with tourists inevitable? To separate fact from fear, "Nova" teams up with leading shark experts in Australia and the United States to discover the science behind the great white's hunting instincts. Do sharks ever target humans or is each attack a tragic case of mistaken identity? Can a deeper understanding of shark senses lead scientists to design effective deterrents and help prevent future attacks? With shark populations around the world plummeting, scientists race to unlock the secrets of these powerful creatures of the deep in their quest to save people -- and sharks.
