Photorealistic Elephant in a Coral Reef

Hyper-realistic underwater scene of a large elephant gracefully swimming through a vibrant tropical coral reef. Sunlight streams through crystal-clear blue water, illuminating multicolored corals, sea fans, and schools of small tropical fish. The elephant's textured gray skin bears subtle algae and barnacles; its tusks catch glints of light. Surrounding them are vivid orange, pink, purple, and teal corals, delicate anemones, and diverse reef life. Bubbles rise as the elephant moves slowly, with a calm, intelligent expression in its eye. Cinematic underwater lighting, ultra-detailed texture, 8k resolution, shallow depth of field to emphasize the subject against a lush reef background.
