  1. nautilus

    A nautilus is an aquatic animal, more specifically a marine cephalopod of the family Nautilidae, inhabiting the Pacific and Indian Oceans. It has a spiral, often beautifully colored shell with inner chambers filled with gas for buoyancy control. Nautilus is also notable for being one of the oldest living species on earth, with a lineage that goes back over 500 million years. The term may also refer to a U.S. nuclear-powered submarine mentioned in Jules Verne’s book Twenty Thousand Leagues Under the Sea.

  1. Nautilus

    Nautilus is the common name of pelagic marine mollusks of the 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. Though it more specifically refers to species Nautilus pompilius, the name chambered nautilus is also used for any species of the Nautilidae. Nautilidae, both extant and extinct, are characterized by involute or slightly evolute shells that are generally smooth, with compressed or depressed whorl sections, straight to sinuous sutures, and a tubular, generally central siphuncle. Having survived relatively unchanged for millions of years, nautiluses represent the only living members of the subclass Nautiloidea, and are often considered "living fossils." The name "nautilus" originally referred to the pelagic octopuses of the genus Argonauta, otherwise known as paper nautiluses, as the ancients believed these animals used their two expanded arms as sails.

Chambers 20th Century Dictionary

  1. Nautilus

    naw′ti-lus, n. a Cephalopod found in the southern seas, once believed to sail by means of the expanded tentacular arms: a kind of diving-bell sinking or rising by means of condensed air:—pl. Nau′tiluses, or Nau′tili.—adjs. Nau′tiliform, Nau′tiloid.—Paper nautilus, any species of Argonauta. [L.,—Gr. nautilos, a sailor.]

U.S. National Library of Medicine

  1. Nautilus

    The sole genus in the family Nautilidae, order Nautilida, comprised of CEPHALOPODS with spiral external shells that are separated into chambers.

Dictionary of Nautical Terms
