Description: Please enjoy my lengthy marine musings on the cultural and ecological impact the 1975 thriller film "Jaws" has had on the survival of sharks and the health of our oceans and fish. Get ready to learn a bunch about White Sharks and how in reality they are not the villains often portray them as, but the victims. Hope you enjoy! Special Thanks to: Dr. Christopher L.
