Fabien Cousteau, Swimming with Sharks
Undersea explorer Fabien Cousteau -- grandson of Jacques -- has spent hundreds of hours studying sharks from inside the belly of the beast, so to speak.
He used a submarine built to resemble a great white shark in order to achieve close encounters with one of the world's most relentless predators.
Cousteau tells Debbie Elliott about his upcoming CBS documentary, Mind of a Demon.
