#ocean#, A surreal 3D coral reef glowing under a bioluminescent eclipse, with crystalline coral structures shaped like fractals and ancient runes, inhabited by ultra-rare, otherworldly sea creatures—jellyfish with translucent wings and geometric patterns, armored octopuses with shifting chameleon metal skins, and ethereal manta rays with trailing iridescent filaments. The water is unusually clear, illuminated by shimmering light beams piercing through an underwater vortex above, revealing a hidden ecosystem that looks half-natural, half-alien. The scene blends science fiction and hyperreal underwater biology, emphasizing color contrast, fine detail, and depth-of-field.
