Submerged Meteor: A 3D Underwater Render

Photorealistic 3D render of a weathered meteor fragment lying on the sandy seabed of a deep ocean trench. The iron-nickel rock is pitted and scorched, partially encrusted with coral, barnacles, and swaying seaweed. Sunlight beams penetrate the clear blue water, creating dynamic caustics and volumetric light that kiss the meteor's surface. Surrounding life includes a curious octopus, schools of small silver fish, and a distant reef with a small submersible for scale. The scene uses cinematic lighting, accurate water refraction, and a cool blue-green color palette with subtle orange bioluminescent accents along cracks.
