Blue Planet: The Collection (Box Set) [Blu-ray]

"The Blue Planet is one of the most breathtaking explorations of the world's oceans ever assembled. Before creating the monumental Planet Earth, the BBC created The Blue Planet: Seas of Life which showed the oceans in a way they had never been seen before - that is, until Blue Planet II. In recent years, our knowledge of what goes in our Ocean has been transformed. Blue Planet II uses cutting-edge breakthroughs in science and technology to explore new worlds and extraordinary animal behaviors."
