The video shows a large fish swimming in the ocean. The fish is mostly grey in color with a white underbelly and has a long, pointed nose. It is swimming near the surface of the water, which is a deep blue color. The fish appears to be alone, with no other fish or objects in the immediate vicinity. The water is relatively calm, with only small ripples disturbing the surface. The fish moves smoothly and gracefully, with its fins and tail propelling it through the water.
