The video shows a seal swimming underwater. The seal is black and has a smooth, sleek body. It moves gracefully through the water, its flippers propelling it forward. The water is clear, and you can see the seal's movements clearly. The seal appears to be alone, and there are no other animals or objects in the frame. The seal's eyes are open, and it seems to be looking directly at the camera. The video is shot from a close-up angle, allowing for a detailed view of the seal's features.
