"Our understanding of ocean life has changed dramatically in the last decade, with new species, new behaviours, and new habitats being discovered at a rapid rate. Blue Planet II, which accompanies an epic 7-part series on BBC1, is a ground-breaking new look at the richness and variety of underwater life across our planet. With over 200 breath-taking photographs and stills from the BBC Natural History Unit's spectacular footage, each chapter of Blue Planet II brings to life a different habitat of the oceanic world. Voyages of migration show how each of the oceans on our planet are connected; coral reefs and arctic ice communities are revealed as thriving underwater cities; while shorelines throw up continual challenges to those living there or passing through. A final chapter explores the science and technology of the Ocean enterprise - not only how they were able to capture these amazing stories on film, but what the future holds for marine life based on these discoveries"--Publisher's description.
