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}, recid = {890018}, pages = {vi, 311 pages, 8 unnumbered pages of plates :}, }
