The Deep

More than 80% of Earth's ocean has never been explored. What lives in that darkness is stranger than anything we have imagined.

The Deep is a journey through the five zones of the ocean - from the sunlit surface to the crushing depths of the hadal trenches - told through the extraordinary creatures that inhabit each one.

Meet the anglerfish, whose males fuse permanently to the female's body and dissolve into her flesh. The siphonophore - a colonial organism 47 metres long, longer than a blue whale, that is simultaneously one animal and thousands. The dragonfish, which shines a red light only it can see, hunting in a private darkness within the darkness. The barreleye fish, whose transparent skull conceals rotating eyes that scientists misunderstood for a hundred years.

This is not speculation. Every fact in this book is real.

Written in the tradition of great nature writing, The Deep combines the wonder of discovery with the precision of science - a descent into the largest, least understood habitat on Earth, and the life that fills it.

The deep sea is waiting.

Stay curious.
