_{The Shanghai Ocean Aquarium in the centre of Shanghai has in its newly constructed modern building with 22.4 000 sqm floor space. And it is made up of 8 major areas with 28 large-scale theme marine life exhibition areas, displaying 300 species and ten thousand more rare fishes from all over the world. Some of them are most unique freshwater and marine life; others are rare aquatic life forms unique of China. All these give visitors a pleasant impression of “experiencing the wonders of the five continents at the bottom of the sea” – and Heiko was kindly invited by these great students of the Shanghai Ocean University.}

_{Two of the endemic Chinese sturgeon species, here in a giant aquarium with other Yangzi River fishes (top two). There is also the only Asian catostomid, Myxocyprinus asiaticus, which has a quite different colour pattern when juvenile (lower).

_{This display of the Chinese giant salamander (Andrias davidianus) is the largest in the world, reaching a length of 180 cm (6 ft), although it rarely – if ever – reaches that size today. It is considered critically endangered due to habitat loss, pollution, and over-collecting, as it is considered a delicacy and also used in traditional Chinese medicine.}

_{The Silver Carp, Grass Carp, Bighead Carp and Black carp and their polyculture system is well displayed here.}
