The video shows a large fish swimming in the ocean. The fish is moving slowly and is visible through the clear water. The fish appears to be a type of shark or ray, with a long body and a pointed snout. The water is calm, and there are no other visible creatures or objects in the vicinity. The sunlight reflects off the water's surface, creating a shimmering effect. The fish's movements are smooth and graceful, and it seems to be undisturbed by the presence of the camera.
