The Hidden World
of Dolphins

Together with marine biologists and professional divers, the filmmakers observe their friendships, enigmatic communication and astonishing abilities in the everyday life of a tropical coral kingdom. The team captures rare and spectacular behavior: dolphins using special corals as a natural pharmacy against skin infections, maintaining lifelong social bonds, sleeping with only half their brain asleep at a time, and using streams of bubbles like weapons during hunts. Set among breathtaking coral reefs, mysterious night dives and deeply emotional encounters, this documentary reveals an underwater society full of curiosity, affection, conflict and joy
