Shark Week, 20th Anniversary

Sharks are some of the most feared and misunderstood creatures on the planet. They've survived for millions of years and are terrifying predatory machines, to be sure, but in reality the chances of being attacked by one of these toothy fish is roughly one in 10 million (in US waters). Discovery pays homage to these awesome predators with programming that explores the science, anatomy, and habits of sharks, as well as true stories about what all swimmers dread: attacks.
