Blue Planet II - BBC Earth

Over two thirds of our Blue Planet is covered by ocean. It's home to the greatest diversity of life on Earth and is our least explored habitat: we have better maps of Mars than of the ocean floor. With this book, take a deep breath and dive into a wondrous world beneath the waves. 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 forests, and glide across the open ocean with humpback whales.
