These four companion books take a dramatic look at our watery planet.

"From space, Planet Earth is blue. It floats like a jewel in the inky black void. The reflection of the sun's light from the vast expanse of water covering its surface creates it gemlike blue color. In the entire solar system, Earth is the only planet that has water in liquid form in such quantities." Scientist have calculated that 70 percent of our planet is covered by water; small wonder that the human being shave always been so fascinated by the oceans and what lies beneath. Today, while we still have so much more of the ocean realm to uncover, we have discovered enough to know that beneath the waves lies a vast treasure-trove of rich and diverse life. Accompanying the television series of the same name, The Blue Planet leads up on a voyage of exploration from the coasts, the very edges of the oceans, to the deep where weird and monstrous fish lurk in a world of perpetual darkness. Along the way we are introduced to a whole host of wonderful creatures -- from tiny copepods to majestic blue whales, and from the grotesque hairy anglerfish, to the amazing tripod fish that stands on its three delicate legs waiting to snap up unsuspecting prey. Complete with a foreword by Sir David Attenborough and 400 full-color photographs, The Blue Planet is the first complete and comprehensive portrait of the whole ocean system.
