In May 2007, 100 years after the opening of the world renowned zoo, Hagenbeck gave the all-clear for its new recreational attraction: the Tropical World Adventure Aquarium. That finally gives the citizens of Hamburg and the steadily growing number of tourists to the Hanseatic city an aquarium of the highest international standard. This new attraction has given Hamburg, the waterside city and “gateway to the world“, an access to the flora and fauna of the equatorial regions. For the visitor, a truly unique world of adventure opens itself up which is designed as though Carl Hagenbeck himself had done it: with barless open enclosures, right up close to the animals. Visitors can see 14,300 exotic animals in their habitat – on land, in the water and in caves. The concept: animals ashore, in water and in caves 300 animals live in the Tropen-Aquarium, some are endangered species from the equatorial regions. In all a total of 14,300 exotic animals have found a home here in Hamburg. The round tour leads the visitor through several theme areas: the tropical and sub-tropical seas, forests and the world of caves. This combination is unique in the world. The species-specific and close-to-nature design of the enclosures together with the fascinating presentation of the animals results in the illusion for the visitor of finding themselves transported into the middle of their habitat. In the biotopes, animals whose territory would also overlap in the wild share a habitat with each other. Visitors are struck by the unbelievable multiplicity of colours and forms of the living coral reef. The multitude of fresh and salt water pools are home to red lion fish, moray eels, unusua lschooling fish and rarities of the aquatic habitat.
