A beautiful exploration of the dark deep sea, where humans rarely go, full of extraordinary living creatures.

Dive into the deep, deep sea! For a long time, scientists thought there was no life down there. But they were wrong! In the abyss, there are creatures that have adapted to the cold and the lack of oxygen or light. Indeed, some can produce light to find food or survive, while others conserve oxygen by moving very slowly. Most of them are surprising and some are even prehistoric, like the vampire squid, giant squid, or sea dragon… This book also discusses the history of deep-sea exploration.
