This is shot at Okinawa Churaumi Aquarium in Japan. It's the 2nd largest aquarium in the world, and the tank you are looking at, the Kuroshio Sea, holds 2 million gallons of water and has whale sharks and manta rays among the other fish. You can follow the jumps to download the 200mb HD version and it's absolutely stunning. Even though I didn't end up going into Marine Biology, I still dig sea life and figured others may enjoy the video.
