Poulpe hyper réaliste dans une pose sous-marine dramatique et symétrique

Hyper-realistic octopus with tentacles wide and pointed downward, dynamic and symmetrical pose. Dramatic cinematic lighting with deep shadows, sharp highlights, and wet-reflective skin. Ultra-fine anatomical detail: suction cups, texture, translucency, realistic muscle tension. Subtle bioluminescent glow along tentacle edges, faint mist or suspended particles in the background. Dark moody environment with high contrast to emphasize shape and depth. Macro-level photorealism, extreme clarity, ultra-detailed, 128K resolution, museum-grade cinematic realism, noise-free, ultra-sharp focus, immersive visual presence. --ar 9:16
