With large-format photographs, the exhibition catalogue takes you through the breathtaking underwater world of our oceans. The images, some of which have never been seen before, allow the viewer to immerse themselves in the lives of beautiful and sometimes strange aquatic creatures, whose clever camouflage and unusual way of life amaze the viewer. The book also documents the consequences of human utilisation of the world's oceans and deals with the topics of marine research and marine protection, thereby illustrating the importance of the Planet Ocean for our entire existence
