The video shows a large sea animal, possibly a seal, swimming in the water. The animal is mostly submerged, with only its head and back visible above the water's surface. It appears to be moving slowly and gracefully through the water. The color of the animal is a mix of dark and light shades, possibly gray or brown. The water is a deep blue color, with small waves visible on the surface. There are no other objects or animals in the video, and the focus is solely on the sea animal.
