Explore coral reefs that shimmer in a kaleidoscope of colours.
Venture to the bottom of the ocean where creatures beyond your wildest imagination live in the dark.
Chase sea otters through kelp forest seas, and glide the open ocean with humpback whales.
'Discover all there is to love about our Blue Planet, the stories of its inhabitants, and realise how you can help protect this wilderness beneath the waves.
'In collaboration with BBC Earth, this illustrated non-fiction book will capture the wonder, beauty, and emotion of the iconic BBC Blue Planet II TV series.'
