PROMPT:
Create a mesmerizing image of an underwater scene, teeming with vibrant marine life, set against a radiant turquoise background that gradates to a deep cerulean towards the top. Incorporate a school of iridescent blue fish, their scales shimmering with an ethereal glow, as they dart past a majestic sea turtle gliding effortlessly through the water. Add a burst of bright orange coral, adorned with delicate, wavy sea fans, and a sprinkling of glittering, gemstone-like seaweed. In the foreground, feature a curious, electric blue octopus, its tentacles curled around a shimmering, crystal-like underwater cave, as it peers out with large, inquisitive eyes. Use vibrant colors to bring this underwater world to life, with a focus on blues, oranges, and yellows, while minimizing the use of pink. The image should exude a sense of wonder and magic, with a photorealistic quality that invites the viewer to step into this enchanting marine realm.
