A great, deep-diving book and an invitation to one of the last spaces that humanity has yet to explore. Pure fascination! Robert Habeck (Federal Chairman of BÜNDNIS 90/DIE GRÜNEN) How is life possible down there, in the dark, cold, and hostile depths of the oceans? Without light, with little food, and under enormous pressure? For a long time, it was believed that there was no life in the deep sea. Yet today we know: Deep in the oceans lies a mysterious and astonishing world that only a few people have ever seen. There live vampire squids, Yeti crabs, Atolla jellyfish, dragonfish, and giant sea spiders. Almost daily, new creatures are discovered. Join us on this expedition and dive down to the ocean floor! Together, we will explore the fantastic habitats of the deep sea with a submarine and uncover incredible facts about the underwater world from the ocean surface to the seabed at depths of over 6,000 meters. This book combines breathtaking art with the latest scientific research. On large canvases, the artist Annika Siems has painted massive images of the deep sea. Her paintings convey impressive visuals of this unknown, dark place. Thus, we can discover the life of the deep sea in spectacular precision and artistry, from the smallest plankton, magnified a thousand times, to the largest whale. Along with marine biologist Wolfgang Dreyer, Annika Siems takes us on a captivating dive through an engaging text. In simple language, it explains how colors disappear from view as one dives deeper, how the life cycle of the deep sea works, what bioluminescence and radiolarians are, how creatures withstand the immense pressure in the depths, and shares many more exciting stories about the mysterious and extraordinary—sometimes eerie—inhabitants.
