This beautiful video was shot by Jon Rawlinson at the Okinawa Churaumi Aquarium — the second largest aquarium in the world.
According to the Wiki:
The main tank called the ‘Kuroshio Sea’ holds 7,500-cubic meters (1,981,290 gallons) of water and features the world’s second largest acrylic glass panel, measuring 8.2 meters by 22.5 meters with a thickness of 60 centimeters. Whale sharks and manta rays are kept amongst many other fish species in the main tank.
