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.
