A video taken from behind glass shows a person wearing a black wetsuit, fins, and goggles "riding" a beluga whale in a tank. The person is positioned face-down with one hand touching the whale. The whale appears to be swimming in a straight line, with the person lying across the whale’s back. The water is a bright blue color, illuminated by overhead lights. The words "正佳极地海洋世界" appear in white text at the bottom of the frame. Another beluga whale is seen swimming in the background above the person and the other whale. Sounds of people are heard in the background.
