S25·E9 Shark Week's 25 Best Bites

Right outside the Golden Gate Bridge in San Francisco is home to some of the biggest great white sharks in the world... but only for part of the year. Teams of scientists from Stanford University's Hopkins Marine Station in Monterey Bay have spent years tagging and tracking these sharks to find out why they come here, why they leave and where they go when they do — out into the Pacific on the Great White Highway. But the sharks have kept much about their lives completely secret, leaving researchers with little information about what they spend their summers doing and almost no idea about where they mate or bear their young. Now, armed with new technologies, the team is hoping to wire the ocean and find out how these sharks live their lives — and why California is one of the biggest stops on the Great White Highway.
