Marine animals manipulate color, depending on how they want to look. They communicate using colors and patterns we don’t see and change position and behaviour, depending on what they want to say. In a teeming social world of camouflage and display, marine animals talk in a language we haven’t yet understood. In a groundbreaking step towards learning to listen, the film unravels the mystery of underwater color and brings a revolutionary understanding of the language of fish. At the cutting edge of marine science, we open our eyes and start to hear what they say. Directed by Guy and Anita Chaumette. Produced by Liquid Motion Film.
