The video shows a large whale swimming in the ocean. The whale is seen from a distance and is moving slowly through the water. The ocean is calm with small waves, and the whale's body is mostly submerged, with only a small part of its back visible above the water. The whale's skin is dark gray, and it appears to be a humpback whale based on its size and shape. There are no other objects or creatures visible in the video, and the whale is the main focus.
