The video shows a large fish swimming in the ocean, surrounded by smaller fish. The large fish has a yellow mouth and is swimming slowly through the water. The smaller fish are swimming around it, creating a beautiful underwater scene. The water is clear and blue, and the light from the sun is shining through, illuminating the fish and the surrounding environment. The large fish appears to be the main focus of the video, with its size and color making it stand out against the smaller fish and the blue water.
