The video captures an underwater scene inside an aquarium or oceanarium, likely located in Saint Petersburg, Russia. The setting is a large tank featuring a sandy bottom, various rock formations, and coral. The water has a greenish tint, and the tank is illuminated from above, creating bright reflections on the water's surface, which show distorted images of overhead lights and possibly visitors. Several fish species are visible, including smaller yellow fish swimming near the bottom and mid-water. A prominent subject is a shark, which swims into view around the 0:02 mark, moving gracefully through the upper part of the tank. Other, less identifiable fish are also seen swimming in the background. In the foreground, information plaques are partially visible on a barrier. One on the left clearly shows Russian text, including the word "Акула" (Shark), confirming the presence of sharks in the exhibit. Another plaque is partially visible on the right. The overall impression is that of a public educational exhibit, offering a glimpse into marine life.
