giant nautilus 3d model

A gigantic nautilus creature with a spiraling shell covered in glowing fractal engravings that constantly shift and rearrange. The shell’s surface glows with faint gold and turquoise patterns like ancient runes. Its tentacles are long, ribbon-like, and semi-transparent, trailing light streams as it swims. A glowing crown-like structure emerges from the top of its shell, emitting soft rays of light like a submerged sun. The surrounding water is filled with slow-moving particles, making it appear like the monarch of a silent underwater kingdom.
