The video shows a large whale swimming in the ocean. The whale is seen from different angles as it moves through the water. The whale's skin is a dark grey color, and it has several small barnacles attached to it. The water is a deep blue color, and bubbles can be seen around the whale as it moves. The whale's tail fin is visible in some shots, and it appears to be quite large. The whale seems to be in a calm state, swimming slowly and gracefully through the water.
