About Nautilus

It is a pelagic marine mollusc of the cephalopod family Nautilidae,the sole extant family of the superfamily Nautilaceae and of its smaller but near equal suborder, Nautilina.Nautilus can be found in the deep blue sea.2017Nautilidae, both extant and extinct, are characterized by involute or more or less convolute 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.

Nautiluses is the largest species in the genus Class:Cephalopoda-info.justplay18.com
