Being addicted to increasing my knowlledge in sharks, I picked this book randomly and was not disapointed. Peter Benchley structures this book extremely well, combining personal experiences with worldwide fishing issues. As a writer, this man has more dives behind him than most people and tells his stories of interaction with marine life from Great Whites to Baracudda, from Killer Wales to Tiger Sharks. In each story he tells, the topic is a potential human threat (that makes the book as thrilling as it is) ie sharks, currents, jellyfish. Benchley, explains his experience in great detail and then in some cases offers a guide in how to counteract these "threats." The icing on the cake for me was the beautifully written fictional story 3/4 of the way through that illustrates the sharks role in nature and how marine life and human life changes for the worse when the sharks are removed. It is evident that the message Benchley is putting across is one of awarness concerning the overfishing and future extinction of sharks. Ironic from the man who wrote Jaws! Fantastic read, if only the fictional story could be portrayed in to a Universal blockbuster to reverse the public opinion on sharks that Jaws created).
