视频展示了一只海龟在海底的场景。海龟的身体主要是绿色和黑色相间的，它的头部和四肢上有明显的纹理。海龟正趴在海底的沙地上，周围有一些水草。它先是用嘴巴触碰着沙地，随后抬起头来，嘴巴微微张开，似乎在观察周围的环境。背景是深蓝色的海水，远处可以看到一些模糊的水草。
The video shows a sea turtle swimming underwater in a clear blue ocean. The turtle is moving gracefully, its flippers propelling it forward as it glides over a sandy seabed with patches of green seaweed. The turtle's shell and skin have a pattern of dark and light markings, and it appears to be feeding or exploring the ocean floor. The scene is serene and captures the beauty of marine life.
A sea turtle is seen underwater, positioned above a sandy seabed with sparse patches of sea grass. The turtle's front flippers are spread out, and it gradually lowers its head towards the seabed. As the turtle's head gets closer to the ground, it begins to sift through the sand with its mouth, creating a small cloud of sediment. The turtle continues to move forward slightly while maintaining its position close to the seabed, persistently using its mouth to gather and consume the sea grass.
