The video captures a close-up view of a stingray swimming gracefully underwater. The stingray's body is predominantly white with a patterned top, and it moves smoothly through the water. The background is a deep blue, suggesting an oceanic environment, with some blurred lights visible in the distance. The stingray glides over a rocky surface, showcasing its elegant movement and the serene underwater setting.
In an underwater scene with a blue background and some rocks, a stingray with a patterned top and a smooth underside swims from the left to the right. As it moves, its gill gradually retracts back into its body. The stingray continues to swim, and its dorsal fin starts to lift and unfold. The fin fully extends as the stingray progresses further to the right.
