From celebrated science writer Riley Black, a beautifully illustrated, compelling deep dive into the life story of the abyss, its ancient creatures, and the scientists and submersibles that have documented them.
 
What lies beneath the surface of the ocean has mystified humankind for millennia. Today, we have explored more of the surface of the Moon than we have the deep sea. What thrives in these mysterious depths, how did these life-forms evolve from ancient life, and how has this environment changed over time as our planet has developed?

Introducing us to the ancient, complex, and fascinating life-forms that have evolved into the marine life we recognize today—from stromatolites, structures created by some of the earliest life billions of years ago and still found today, to yeti crabs, bioluminescent firefly squid, and giant jellyfish—Deep Water is an eye-opening journey into the world far beneath the waves. Our guide, brilliant science communicator and self-described “fossil fanatic” Riley Black, has studied marine biology and paleontology, and she brings her vast knowledge and inimitable voice to our voyage. Through text and image, Black leads us further and further into the depths to reveal how this unique and largely unexplored habitat came into being, what lives there and why, how it has evolved, and what the future will bring in this dark and mysterious environment.

Frigid, dark, and energy-deprived, the deep sea was long considered hostile to life. However, new sampling technologies and intense international research efforts in recent decades have revealed a remarkably rich fauna and an astonishing variety of novel habitats. These recent discoveries have changed the way we look at global biodiversity. In Deep-Sea Biodiversity, Michael Rex and Ron Etter present the first synthesis of patterns and causes of biodiversity in organisms that dwell in the vast sediment ecosystem that blankets the ocean floor. They provide the most comprehensive analysis to date of geographic variation in benthic animal abundance and biomass. The authors document geographic patterns of deep-sea species diversity and integrate potential ecological causes across scales of time and space. They also review the most recent molecular population genetic evidence to describe how and where evolutionary processes have generated the unique deep-sea fauna. Deep-Sea Biodiversity offers a new understanding of marine biodiversity that will be of general interest to ecologists and is crucial to responsible exploitation of natural resources at the deep-sea floor.
