About This Dataset
Largest Aquariums in the World
Public aquariums are ranked by the total volume of water in their tanks, which determines what species they can keep - whale sharks and manta rays need volumes that most facilities cannot provide. This chart lists the largest aquariums by total capacity in millions of litres.
Analysis
Chimelong Spaceship in Hengqin holds 75.4 million litres, 1.55 times the 48.8 million of Chimelong Ocean Kingdom. 3 of these 12 aquariums are in the United States, the most of any country on the chart. The 12 together hold 408.2 million litres, and the top two alone account for 30% of it - the gap between the biggest facilities and the rest is far wider than the gap among the rest.
