Shark with Steve Backshall

Steve explores the radical variety of sharks in the Atlantic Ocean and marks the start of a global journey in the so-called shark capital of the world, the Bahamas.

The naturalist learns about the sharks of the Indian Ocean, which despite finding ways to adapt to the environment, face threats from climate change, pollution and overfishing.

In search of shark hotspots in the Pacific, Steve visits Cocos Island off the coast of Costa Rica. It is the tip of a huge underwater volcano. But what attracts the sharks here?
