Fabien Cousteau is an aquanaut, ocean conservationist, and documentary filmmaker. As the first grandson of Jacques Cousteau, Fabien spent his early years aboard his grandfather's ships Calypso and Alcyone, and learned how to scuba dive on his fourth birthday. From 2000 to 2002, he was Explorer-at-Large for National Geographic and collaborated on a television special aimed at changing public attitudes about sharks called "Attack of the Mystery Shark". From 2003 to 2006, he produced the documentary "Mind of a Demon" that aired on CBS. With the help of a large crew, he created a 14-foot, 1,200-pound, lifelike shark submarine called "Troy" that enabled him to immerse himself inside the shark world.

Jacques-Yves Cousteau, was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful open-circuit self-contained underwater breathing apparatus (SCUBA), called the Aqua-Lung, which assisted him in producing some of the first underwater documentaries.
