The video shows a large fish swimming in the ocean. The fish is silver in color and has a long body with a pointed nose. It is swimming near the surface of the water, which is a deep blue color. The fish moves gracefully through the water, its fins and tail moving in a smooth, coordinated manner. The sunlight reflects off the water, creating a shimmering effect. There are no other fish or objects visible in the video, and the focus is solely on the large fish.
