24 dive sites that every diver should see in their lifetime. 24 reports that together reflect the entire fascination of diving: written by authors who work for leading diving magazines and illustrated by some of the best photographers in the world. Underwater describes places that couldn't be more different: sharks and mantas, wrecks and caves, colorful reef worlds or dives under ice - sometimes close by, sometimes far away. However, all reports share one common theme: they tell of the addiction that the blue planet Earth exerts underwater on many people and of wonder worlds that remain closed to most.
