Golden Retriever in Atlantis: 3D Underwater Render

Ultra-detailed photorealistic 3D render of a curious golden retriever exploring the sunken city of Atlantis. The dog is wet and gleaming, fur slick with water. Surroundings include ancient Atlantean architecture: moss-covered coral-torn columns, shattered statues, and glowing blue runes etched into marble. Teal and sapphire water with shafts of sunlight piercing down, caustics dancing on ruins, bubbles rising, and swaying kelp. Bioluminescent crystals cast a soft azure glow. The scene is cinematic, with realistic water refractions, depth, and meticulous texture on fur, stone, and sea life.
