Underwaterworld Trilogy

A harsh and competitive environment, the Underwaterworld contains a wide array of marine animals surviving together in a wondrous realm. In "Deep Encounters," the harsh reality of life underwater is that it always pays to watch your back! This film reveals the hunters and the hunted--including sharks and their prey. "Ocean Allies" illustrates the friendships and relationships creatures form to help each other survive, from shoaling to living on another creature's back--or even inside! "Blue Voices" examines how air-breathing mammals and other unlikely animals cope with the special demands of aquatic life, including high pressure and lack of oxygen.
