The water is clear and blue, with sunlight filtering through from above. The turtle's shell is brown and textured, and its flippers are moving in a steady rhythm. The ocean floor is visible, covered in various types of marine life and coral. The turtle appears to be alone in the water, with no other sea creatures visible in the video.
