Xiamen Underwater World contains more than 10,000 marine animals covering 350 marine species from all continents and oceans. Get your cameras ready when you are at the entrance as there is a uniquely-designed octopus sculpture there. But, if that doesn't interest you, then head straight to the 80 meters long underwater tunnel where you can see the concave fish ponds on both sides and "swim" with tens of thousands of fishes coming in different shapes and sizes as they explore the magnificent underwater world. If you happen to be around during feeding time, the experience of seeing hundreds and thousands of fishes swirling together fighting for food is quite a sight.
