Author William McKeever argues that we misunderstand sharks, that they're not the terrifying man-eating killers of "Jaws" fame, but essential parts of our fragile ocean ecosystem. And they need our protection.

William McKeever is a conservationist, founder of Safeguard The Seas, and author of the new book is "Emperors Of The Deep: Sharks--The Ocean's Most Mysterious, Most Misunderstood, and Most Important Guardians."
