"A Beluga whale has become a sensation at an aquarium after learning how to blow halo-shaped bubbles. The extraordinary sight was captured on camera by photographer Hiroya Minakuchi at the Shimane aquarium in Japan. He said: ‘This beluga started making bubble rings when she was seven. And a couple of years ago she developed her technique. Now she blows the water from her mouth to make a current, which is not visible for us underwater. She then blows air from her blow hole into the current and that makes a ring shape.’"
