context_page_description: Nautilus is a genus of cephalopods in the family Nautilidae. Species in this genus differ significantly in terms of morphology from those placed in the sister taxon Allonautilus. The oldest fossils of the genus are known from the Late Eocene Hoko River Formation, in Washington State and from Late-Eocene to Early Oligocene sediments in Kazakhstan. The oldest fossils of the modern species Nautilus pompilius are from Early Pleistocene sediments off the coast of Luzon in the Philippines.
  The common term Nautilus usually refers to any extant members of the Nautilidae family.The entire Nautilidae family, included all species in genus Nautilus and genus Allonautilus, was listed on Appendix-II of Convention on International Trade in Endangered Species of Wild Fauna and Flora.
  The current consensus is that the genus consists of four valid species, although this remains the subject of debate. Nautilus are typically found in shallow waters in tropical seas, mainly within the Indo-Pacific. The genus Nautilus has previously included several species represented in the fossil record, however these have since been reclassified, and the genus now only includes extant species.
