Sharks have roamed the planet’s waters since before the dinosaurs, but only recently have we begun to understand the lives of these powerful predators in the ocean. Fifty years after Jaws shocked audiences in theaters, we open the National Geographic archives to reveal the true story of 20th-century women leading shark science and dive into the cutting-edge conservation work of shark researcher and National Geographic Explorer Jess Cramp. Swim alongside her under the vibrant waters of the South Pacific to find out what it truly means to save sharks.
