Nautilus (from Greek 'sailor') is the common name of marine creatures of cephalopod family Nautilidae, the sole extant family of the superfamily Nautilaceae and of its smaller but near equal suborder, Nautilina. It comprises six living species in two genera, the type of which is the genus Nautilus.

The Chambered Nautilus (Nautilus Pompilius) is the best-known species of nautilus. The shell, when cut away, reveals a lining of lustrous nacre and displays a nearly perfect equiangular spiral. The shell exhibits countershading, being light on the bottom and dark on top. This is to help avoid predators because when seen from above, it blends in with the darkness of the sea, and when seen from below, it blends in with the light coming from above.

Having survived relatively unchanged for millions of years, nautiluses represent the only living members of the subclass Nautiloidea, and are often considered "living fossils."
