The Nuremberg Zoo (Tiergarten Nürnberg) is one of the two remaining in Germany, where dolphins are kept (the second is in Duisburg). In Europe, the number of such zoos is steadily declining, as the discontent of ecologists grows. They believe that animals with such high intelligence cannot live in such a limited space together. They become too aggressive.
The dolphinarium has problems with the survival of newborn dolphins and the leakage of the new pool, and continues to be under constant criticism from ecologists. But for now, the zoo would like to keep the dolphinarium.
