Animal trainer performs synchronized underwater dance routine - with a beluga whale

This is the moment an animal trainer performed a synchronized underwater dance routine with - a beluga whale.

Funny video shows Duo Duo, a 12-year-old male beluga whale, moving his head around and thrashing his body to the beat of the music.

Xu, an animal trainer at the aquarium in Danzhou, China, often dances with Duo Duo.

Xu, who's also a dancer, says she doesn't perform specific moves but Duo Duo always mimics her and follows along.
