The nautilus belongs to the phylum Mollusca, which includes a diverse group of invertebrates known as mollusks. Within this phylum, nautiluses are classified under the class Cephalopoda, which also includes squids, octopuses, and cuttlefish. Nautiluses are unique for their coiled, chambered shells and are often referred to as "living fossils" due to their ancient lineage.
