Expedition Great White: Catching the Ocean's Largest Predatory Fish

Contents

Great white sharks. They're not just among the ocean's biggest creatures, they're among its fiercest.

They can detect tiny amounts of blood in water up to three miles away. They make about half of all the shark attacks reported in a given year.

But in National Geographic Channel's "Expedition Great White," which premieres Monday, scientists and sports fishermen do the unimaginable: They wrangle the multi-ton creatures, haul them aboard their ship, attach tracking tags, take measurements and DNA samples and then release them unharmed. All in the name of science.

The largest predators in the ocean (they can extend to more than 20 feet and exceed 5,000 pounds), great white sharks are listed as an endangered species because of overfishing, accidental catching and other factors.
