Sharks

The extraordinary journeys of sharks are revealed by Michael Bright in the beautiful and sweeping Sharks.

Bright shines attention on the thousands of miles some sharks traverse through the world's oceans, taking weeks or even months to reach their destinations. He highlights sharks that perform there-and-back vertical migrations, rising from the depths to cover a mile or more in a single day. He compares the local movements of whitetip reef sharks with the epic ocean-spanning migrations of dusky sharks.

Why, though, do sharks travel such distances, and how do they find their way? Cutting-edge research and innovative tracking technologies, such as acoustic devices and satellite tags, are providing researchers with the tools to answer those questions. Bright explores the latest research and explains some of the many mysteries of shark migration.

Sharks explores the migrations of these fascinating creatures, revealing the inherent dangers of their wandering. For, while attacks on humans make the headlines, it is the sharks themselves who face the greatest threat, from humans in return, as they move through the ocean currents.
