Coral Reef Glowing Jellyfish

A deep-sea coral-reef scene, a blue-toned tropical underwater world with large expanses of healthy, thriving colorful living coral, including branching coral, brain coral, plate coral, and soft sea-fan coral, with large schools of tropical fish weaving naturally among them. The foreground is crisp and vivid; the distance gradually turns bluer and grayer with reduced contrast. Natural light from above is filtered through the seawater into soft volumetric light, with fine suspended particles and a gentle sense of flow in the water, the soft corals swaying lightly and the fish schools moving smoothly and in coordination. Add a group of semi-transparent pale-lavender glowing jellyfish slowly appearing, 8-12 of them, in varying sizes. Their bell bodies carry a soft bioluminescent effect, tentacles drifting gently with the current, the tentacle tips bearing faint purple light points. The jellyfish are proportioned harmoniously with the corals and fish, the glow soft and not harsh, forming dreamy light spots against the dark seawater background. The jellyfish swarm's movement path is natural, rising in a slow ascending spiral, with some jellyfish swimming past in front of the lens to produce a slight lens-flare effect. Maintain the underwater blue-toned lighting, the jellyfish glow coexisting harmoniously with the faint reflections of the surrounding coral. As the jellyfish swarm swims, they produce bubbles that rise and form the word "Seedance" in the sea.
