How mammals conquered the ocean 50 million years ago
In short: Whales represent a biological paradox: mammals that returned to the sea. This documentary explores how these giants adapted to underwater life, developing unique hunting techniques and complex communication systems to survive in the deep.
More than 50 million years ago, cetacean ancestors transitioned back into the ocean. Despite the challenges of breathing, nursing, and sleeping underwater, they successfully adapted by evolving mysterious communication methods and specialized hunting behaviors.
The film follows oceanographer François Sarano as he investigates specific behaviors, such as the tail-slapping of Sperm Whales and the unique ability of Valdes Peninsula Orcas to beach themselves to catch prey. These mysteries are explored across diverse locations including Polynesia, Florida, Mexico, and Argentina.
