      abstract = {From the Jaws blockbusters to Shark Week, we are  conditioned to see sharks as terrifying cold-blooded  underwater predators. McKeever shows that sharks are  evolutionary marvels essential to maintaining a balanced  ecosystem. We can learn much from sharks, he argues, and  our knowledge about them continues to grow. Here he  examines four species: Mako, Tiger, Hammerhead, and Great  White. He goes back through time to probe the shark's  pre-historic secrets, and takes us on a pulse-pounding tour  around the world to see sharks up close in their natural  habitat. -- adapted from jacket},
