Chimelong Ocean Kingdom Whale Shark Exhibit Aquarium (珠海长隆海洋王国), located inside the immense "Chimelong International Ocean Resort" theme park in Hengqin (China), is the largest and best aquarium in the world. It features none less than five whale sharks as well as an abundance of other species like manta rays, corals, and sharks.

Chimelong Ocean Kingdom has set the Guinness World Records for having the world's biggest underwater viewing dome and the world's largest aquarium tank. A giant sixty-three meters blue whale shark statue towers over the world's largest aquarium, making it also a remarkable sight from the outside. The award for the world's largest tank was given to this aquarium because the record volume of 22.7 million liter includes strictly the main tank (while the 24-million-liter capacity of the Georgia Aquarium consists of the main tank, rear holding tank, filters, and pipes).

The stunning aquarium can be reached from Macau by bus or taxi in about 30 minutes or from Hong Kong in ca. 2 hours.
