In the video, a shark is seen swimming in the ocean near a coral reef. The shark appears to be a grey color and is swimming in a slow and steady manner. The coral reef is a mix of different colors, including brown, green, and red. There are also small fish swimming around the reef. The water is clear, and the lighting is natural, suggesting that the video was taken during the day. The shark seems to be the main focus of the video, with the camera following its movements as it swims around the reef.
