Discover the mighty fish that have ruled the oceans since prehistoric times in this picture-packed guide to the extraordinary shark family.

Did you know that sharks first appeared in the oceans 200 million years before the dinosaurs, and that they have an electrical sixth sense that helps them locate their prey? How dangerous is a great white shark? Can a whale shark really grow as big as a city bus? If you find yourself seeking the answers to these questions, then this may be the book for you!

Discover where they live, why they are hunted, and what can be done to protect them. The book even takes you inside a shark to learn how it eats and breathes. It explains, too, how they can swim so fast and how different tail shapes affect the way each species moves.
