A colossal, shimmering jellyfish spaceship hovers above a futuristic underwater city, its translucent, neon-lit tendrils illuminating the ocean depths with hypnotic, rainbow hues. Sleek, bioluminescent skyscrapers and coral-shaped towers stretch up from the sea floor, their designs inspired by organic life forms. In the foreground, a team of divers in sleek, exo-suits floats in awe, their helmet lights casting a soft glow on the alien marine creatures swimming around them. Bubbles and rays of bioluminescence create a mesmerizing symphony of movement and color, where electric blues and glowing purples blend seamlessly into the dark, aquatic expanse.
