Shanghai's biggest and best aquarium, and Asia's largest, opened in 2002 in Pudong, next to the Oriental Pearl TV Tower. Its state-of-the-art facilities boast 28 exhibit areas for more than 10,000 sea creatures from all continents: sharks, jellyfish, turtles, lionfish, sea otters, Yangzi sturgeon, and more. The centerpiece is the massive, sparkling, glass-surround observation tunnel. Adventurous visitors can make special arrangements to dive in the shark tank, though it could well cost you an arm and a leg.
