The video shows a seal swimming in the water. The seal is mostly submerged, with only its head and part of its back visible above the water's surface. The water is clear, and the seal's skin is a mix of gray and black, with some white spots. The seal moves slowly and gracefully through the water, occasionally turning its head to look around. The background is blurred, but it appears to be a natural body of water, possibly a lake or ocean.
