The video shows a large whale shark swimming in the ocean. The whale shark is dark gray with white spots on its body and is swimming slowly through the water. The ocean water is a clear green color, and the sun is shining brightly, creating a beautiful contrast with the whale shark. The whale shark's fins are visible as it moves through the water, and its tail is seen propelling it forward. There is no other marine life visible in the video, and the whale shark is the main focus.
