In 1988, American sailor Terry Kennedy encountered a six-meter-wide Pacific manta ray near San Benedicto Island, naming him Willy. Their unique friendship, documented over decades, is now the subject of 'The Last Dive,' a film exploring their bond and its impact on marine conservation.

Kennedy's interactions with Willy, including rides through underwater volcanic peaks and assistance in locating abandoned nets, highlight the intelligence and social nature of manta rays. The documentary aims to inspire a new generation to appreciate and protect ocean life.

Manta rays, with wingspans up to 7 meters and weighing up to 2 tons, are among the largest fish in the ocean, known for their intelligence and unique spot patterns used for individual identification.
