The video shows a large fish swimming in the ocean. The fish is dark in color and has a streamlined body. It is surrounded by smaller fish that are swimming around it. The water is a deep blue color, and the lighting is dim, creating a serene underwater atmosphere. The large fish moves gracefully through the water, its fins and tail gently propelling it forward. The smaller fish seem to be following the larger fish, possibly as a form of protection or companionship. There are no visible titles, subtitles, or informative text in the video.
