Meet the mighty fish that have ruled the oceans since prehistoric times

A 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?

Find out all the answers in Eyewitness Shark, and many more weird and wonderful facts. Discover where they live, why they are hunted, and what can be done to protect them. Read about the broad finned angel sharks, the flathead hammerhead, and learn how the cookiecutter, wobbegong, and megamouth sharks get their names. Learn, too, about their relatives, the manta rays and skates.

Eyewitness Shark even takes you inside a shark to learn how it eats and breathes. It explains, too, how they can swim so fast and different tail shapes affect the way each species moves. You’ll see for yourself how a lemon shark is born, and which looks stranger, the hammerhead or the horn shark.
