"Create an image featuring a single jellyfish, crafted from jelly, glowing within the dark yet enchanting blue depths of the sea. This jellyfish should appear to radiate its own light, illuminating its surroundings with a gentle luminescence. Its delicate, jelly-like form should be highlighted, showcasing its graceful movement as it floats through the ocean. The scene should be purely visual, with no text, capturing the serene and mystical beauty of this jelly creature in its natural, underwater world.  --ar 16:9
