An aquarium you walk underneath so you are completely surrounded by water giving you a 360 degree view of some of the world's most dangerous aquatic animals and fish from the world's tropical waters. More than 2,000 animals can be seen here in 14 exhibits from a 100-ft/30-m nurse shark to a tiny clown fish. Divers in the aquarium talk about the animals and answer questions via a high-tech underwater communications system. The largest display of golden saltwater crocodiles outside Thailand can be seen here too. This is a seriously endangered species as there are only 12 left in the world. Other animals include moray eels, southern stingrays, angelfish, puffer fish, jellyfish and serpents and dragons featuring green tree pythons, known for their vivid green colour and razor-sharp teeth. A touch pool includes sharks, rays and horseshoe crabs. Certified divers staying at the Mandalay can dive with the sharks in the largest 'Shipwreck' exhibit.
