Iconic Spiral Shell of the Tropical Indo-Pacific Nautilus Pompilius

Fascinating shell of Nautilus pompilius, a marine cephalopod mollusk belonging to the Nautilidae family. The spiral shape and the distinctive brown striations on a cream background make this specimen a subject of great naturalistic interest. The nautilus is one of the most peculiar cephalopods: its shell grows by forming successive internal chambers, separated by thin walls and pierced by the siphuncle, a structure that helps regulate buoyancy. The species lives in the tropical waters of the Indo-Pacific and has a scientifically documented presence in Indonesian waters, including those of Ambon and the Moluccas. It is valued for the geometry of its spiral, its natural coloration, and its significance in the evolutionary history of mollusks. An specimen of interest for shell collectors, malacology enthusiasts, and natural history collections.
