The video shows a shark swimming in the ocean with a diver nearby. The shark is large and has a pointed nose, and it is swimming in a blue ocean. The diver is wearing a wetsuit and is holding a camera, capturing the moment. The shark swims past the diver, who follows it closely. The water is clear, and the lighting is natural, suggesting that the video was taken during the day. The shark's movements are slow and graceful, and it appears to be undisturbed by the presence of the diver.
