One of the largest aquariums in Europe, this South Bank attraction boasts 350 species of fish -- everything from British freshwater species to sharks that once patrolled the Pacific. Observe the bountiful riches of the coral reefs of the Indian Ocean, and what lurks in the murky depths of the Atlantic and Pacific oceans, including an array of eels, piranhas, rays, jellyfish, and other denizens of the deep. You ford a freshwater stream into a mangrove swamp to reach a tropical rainforest. The seawater, incidentally, is just normal Thames water mixed with 8 tons of salt at a time.
