Coral reefs are dying worldwide and are likely to disappear from this planet in the foreseeable future. Over the past decades, the authors have documented the wildlife of the Indo-Pacific coral reefs through thousands of dives, capturing it in a variety of photographs and identifying species with the active help of numerous international scientists. The majority of the images were taken with a twin-lens 6x6 Rolleiflex 3.5F medium format camera in a Rolleimarin housing, providing a unique collection that is now available to all interested parties in three volumes: Volume 1: Lower Animals / Stony Corals, Volume 2: Mollusks / Sponges, Volume 3: Echinoderms / Fish.
