Our understanding of ocean life has changed dramatically in the last decade, with new species, new behaviors, and new habitats being discovered at a rapid rate. Blue Planet II, which accompanies an epic 7-part series, is a ground-breaking new look at the richness and variety of underwater life across our planet. With 300 breathtaking photographs and stills from the BBC Natural History Unit's spectacular footage, each chapter brings to life a different habitat of the oceanic world.
