The video shows a close-up of a dolphin swimming in clear blue water. The dolphin has a smooth, light grey skin and a long, curved snout. Its eyes are small and dark, and it has a small dorsal fin on its back. The dolphin is moving gracefully through the water, occasionally turning its head and flipping its tail. The water is calm, and there are no other visible creatures or objects in the frame. The lighting is natural, suggesting that the video was taken during the day.
