The background shows a serene underwater environment with a sandy ocean floor and some scattered rocks. The overall scene conveys a sense of calm and the beauty of marine life.
A sea turtle is swimming in the ocean, surrounded by a clear blue environment with visible coral reefs on the ocean floor. The turtle begins to move its front flippers outward, preparing to swim. It continues to extend its flippers fully to the sides, creating a graceful motion. The turtle then starts to bring its flippers back towards its body, completing the swimming motion. Finally, the turtle's flippers are fully retracted, and it continues to swim forward.
