Although many people only associate the German Oceanographic Museum with the museum itself, it now includes four sites: the Oceanographic Museum itself, the Natureum at Darsser Ort lighthouse, the Dänholm Nautineum and the MeeresWelten (ocean worlds) interactive exhibition.
The Oceanographic Museum remains the most popular site and since the end of January has had an amazing new visitor attraction - a 350,000 litre aquarium for turtles. It is the only turtle enclosure of its size in Germany and provides a home for three species threatened with extinction. Four female turtles can be observed living as if in the wild in the 13 by 6 metre aquarium, one loggerhead and one hawksbill and two green turtles. Visitors can watch these huge creatures through a 21cm thick glass screen, eight metres by three metres in size.
