This video says about itself:
Allya the Beluga whale at an aquarium in western Japan has learned to blow bubble rings. In the wild, some dolphins and whales blow bubble rings by inhaling air through their blowholes and releasing it through their mouths underwater. But thanks to scuba diving equipment, Allya can do it anytime.
Allya clearly loves interacting with her audience. She aims the bubbles at spectators as they peer in through the glass.

The beluga whales of Alaska’s Cook Inlet are endangered and require additional protection to survive, the US government declared yesterday, contradicting Alaska Governor Sarah Palin who has questioned whether the distinctive white whales are actually declining.
It was the Republican vice presidential candidate‘s second environmental slap from Washington this year. She has asked federal courts to overturn an Interior Department decision declaring polar bears threatened under the Endangered Species Act.
