This is the Kuroshio Sea, an exhibit at the Okinawa Chiraumi Aquarium in Japan. John Rawlinson shot a few minutes of HD and put it to music. You really should watch it. I’m torn between beautiful and sad. The animals are gorgeous and really well displayed but most of them travel hundreds of miles a week in the wild and though this is a huge tank, it’s still pretty small compared to what these critters are used to.
