Amazing footage, filmed yesterday, of a beluga whale in an enclosure at Vancouver Aquarium showing an interest in a visitor's music box.

The video shows the whale approaching the aquarium glass while the visitor winds up the music box to play a lullaby.

The animal then appears to listen to the music and dance in the water.

"This beluga couldnt get enough of the lullaby and continuously smashed his melon to the glass as if trying to understand the music," the filmer wrote online.

"He dances in delight to a sweet melody - My hope is to bring some entertainment and joy to their lives."
