THE “KUROSHIO SEA” tank at the Okinawa Churaumi Aquarium in Japan is one of the largest aquarium tanks in the world, with nearly two million gallons of water and a spectacular array of sharks, rays, and other fish. In fact, it’s the fourth largest in the world (though it says it’s the second largest on the Vimeo page; the video was made four years ago), recently having been bumped back a bit by the 12.87-million-gallon Chimelong Ocean Kingdom Aquarium in China.

But for my money, Okinawa Churaumi is the best. The reason? This video. It’s one of the most relaxing, zen films I’ve ever seen. This is what we would have as our screensavers if screensavers were still a thing people had.

And if the Chimelong Ocean Kingdom would like to prove me wrong, they can feel free to make a super mellow video too. Go ahead, Chimelong: I dare you.
