Ali and Blue, the rare albino alligators, are the latest attractions in this incredible labyrinth of underwater passageways, tanks, and enclosures that mimics the mythical lost city of Atlantis. Boasting an impressive 65,000 exotic sea creatures, this aquarium is a sight to behold, with dancing jellyfish, swooping rays, and mysterious groupers lurking in the depths. The highlight of the experience is the 11.5-million-litre Ambassador Lagoon – for an extra fee, visitors can snorkel or dive with the fish in this gigantic tank.
