This mind-blowing aquarium has 15 tanks, each representing a specific region of the Pacific Rim. The central tank, representing the Pacific Ocean, is 9m deep and home to a gazillion fish and whale sharks, mesmerising visitors as they spiral down from the 8th floor to the ground.
We don't love the idea of putting Whale Sharks in a tank but here are the details in case you want to protest or marvel at them.
