In the Anatomy section, the tentacles are described as "undifferentiated". However, later in the article, it reads: "Two pairs of tentacles are separate from the other 90-ish, the pre-ocular and post-ocular..." -- a bit confusing/contradictory. 68.45.217.130 ( talk) 00:26, 23 November 2012 (UTC)
Just like octopus, this is another Latinized Greek word with more than one accepted plural (17th century Latin from Greek nautilos sailor). If there are no objections I'd hereby like to establish that nautiluses is preferred over nautili for the use in plain English articles. Femto 20:53, 5 Nov 2004 (UTC)
Marcos of Pojoaque insists on the use of "nautili" as the plural form. Much cooler way to say it after all.
I must agree that "nautili" is much cooler to say. Jedi of redwall 02:26, 13 May 2006 (UTC)
As a lover of fine elocution, I must say I prefer the pseudo-latin plural form, nautili, but both are acceptable. (Nautilus might also easily be used for the plural, as well as the singular form, but I have never seen this used. Irrelevently, I also believe that the Greek plural would be 'Nautilodes', though I am not certain.) This is, however, a discussion for Wiktionary. I must insist that this be continued in the article below. Currently, the Wiktionary page accepts both. [1] Brandonrc2 ( talk) 05:37, 30 December 2008 (UTC)

As an aside, the split between Chambered Nautilus makes sense from a classification standpoint, but it really needs a more prominent link than just those in the lists, until the other topics are expanded. Femto 16:22, 16 Nov 2004 (UTC)
A tad random, perhaps, but I believe by 'cephalapod expert', you are referring to marine Biologists. (This science somewhat overlapping with paleontology, in this case.) Brandonrc2 ( talk) 05:36, 30 December 2008 (UTC)
Confused or Confusing? They may all have the same root, but they refer to very different things. Nautiloidea is a subclass of cephalopods with its beginning in the Late Cambrian some 500 million years ago, depending on whose time scale you use. Nautilida is an order within the Nautiloidea, along with other quite different orders, that began some 410 million years ago in the Devonian. The Nautilidae is a family within the Nautilida that made its first appearance in the Upper Triassic, some 210 million years ago. And of course Nautilus is one genus out of a number in the Nautilidae, confined to the Cenozoic. The taxonomy is basic HS biology. The paleontology may be something else.

Would it be possible to put a picture of the actual animal on this page, in addition to the shell? Joblio 10:35, 21 Feb 2005 (UTC)
Can the image of a live Nautilus be placed back on this page, as well as the page for the Chambered Nautilus? The shell doesn't say much for an extant species. Ryulong 02:43, 8 February 2006 (UTC)
Thank you SO much, that's very helpful.
I've added a few words on log spirals and golden ratio to the main page.
I expect the golden section bit to be critizied, so here is my answer to that criticism (a bit premature, perhaps...).
-- Niels Ø 15:06, Mar 18, 2005 (UTC)
Where the article says "The name originally referred to the Argonauta, otherwise called the paper nautilus, because it was alleged to use its two disk-bearing arms as sails," would it be reasonable to add (cf. Arist. H.A. 622b)? H.A. for Historia Animalium, the customary Latin title for the Greek work. Aristotle's work will most often prove to be the source of this error in pre-modern writings.
Also, Callimachus, epigram XIV, is a short dedication to Aphrodite spoken from the point of view of the nautilus shell that is dedicated. Lines 3-6 concern its movement, using the same mistaken biology of a foot-sail. Since the entire epigram is about the nautilus, it might be a nice note somewhere.
I believe the distribution of the nautilus includes the Indian Ocean. I say this because I have a shell recovered off the West Coast of Australia. I also read on other encyclopaedias that it is found in the Indian Ocean. —Preceding unsigned comment added by 139.168.237.198 ( talk • contribs)
Is there any source explaining why nautilus has not evolved a lens for its eye? I was reading The Blind Watchmaker, and Dawkins says that he is "worried" about this, since it is such a seemingly simple adaptation, and suggests that the best available explanation is that the necessary mutations can't arise, based on nautilus embryology. If there is any mention of this in the scientific literature, I should like to see it added. Bueller 007 ( talk) 15:18, 19 November 2007 (UTC)
On a related point, the article refers to the creature having a pinhole 'lens,' which I think is a bit inaccurate since it has an open pinhole through which water can flow, but there's not actual transparent 'lens' as such. -- Eamonnca1 ( talk) 18:48, 3 April 2009 (UTC)
Are their eyes one of the best or one of the worst. In the 1979-Life on Earth(Ep 2: Building Bodies) documentary David Attenborough says '...their eyes although they don't have lenses are the best of any creature we have seen so far.' I know the source is a bit out dated but maybe some one that better understands this organism can edit the text if they see fit. Meteislam

These creatures have become synonymous with dinosaurs in popular culture, though little mention is made of their status as 'living fossils' (Yes, it is mentioned, but no details are given. This isn't just a squid in a snail shell! This is comparable to seeing a dinosaur today!) I know many similar cases have occured, but this is a very noteworthy one, since this creature is actually very well-known. Most 'living fossils' that are discovered have been relatively unknown. (To the unstudied. You don't need to be a paleontologist to know you're looking at a T-Rex, but anyone might pass by a plant or bird thought to be extinct and never realize it.) Anyone can recognize a nautilus. I simply think more information should be supplied to this matter. Very few people I talk to believe that they are around today, and some thought it was a hoax even after I showed them this article. When I first read of the Marine Biologists' discovery, I was shocked. Brandonrc2 ( talk) 05:36, 30 December 2008 (UTC)
It's pretty confusing to have Nautilus as well as Nautilus (genus). As far as I can see, Nautilus refers to extant memebers of the order Nautilidae. This is a rather unscientific distinction, which is certainly not implicit in the article's title. I would suggest merging Nautilidae in to Nautilus; I'm not sure which name is more appropriate. Any comments? Martin ( Smith609 – Talk) 19:07, 13 August 2009 (UTC)
Not a good idea. Merging the two, especially a higher taxon (Nautilidae) under a lower taxon Nautilus would only be misleading and confusing. Nautilus is a specific genus with a range from the Oligocene to the recent, unless an Eocene species is included. The Nautilidae is a family that includes not only Nautilus but Cenoceras, Eutrephoceras, Carinonautilus, Obinautilus, and Pseudocenoceras, the latter all extinct. The Nautilidae have a much longer range than Nautilus, beginning in the Upper Triassic.
Were it not for the fact that the Nautilus article is rather extensive, it might be another thing to incorporate the material within Nautilidae. But I don't recommend it.

The "Linne" links for nomenclature sources are going to some obscure town. Can we get the links fixed by pointing them to whoever named the species/genera? Wayne Hardman ( talk) 01:13, 14 November 2009 (UTC)
Shouldn't Nautilus repertus be included? It's included on the chambered nautilus page, but not here for some reason. Since this was the first "species" to be breed in captivity, it seems notable enough for inclusion. Jojuko ( talk) 01:15, 25 January 2010 (UTC)
It says 'Fossil records indicate that nautiloids have not evolved much during the last 500 million years. Many were initially straight-shelled, as in the extinct genus Lituites. They developed in the Late Cambrian period and became a significant group of sea predators during the Ordovician period.' However, it's temporal range shows 'Triassic' which is only 200-250mil years ago to present. Why does this not go much further back? Based on that statement, this should go to the 'Cambrian' era in the graphic. I'm not expert, can somebody confirm this before a change is made? Zkbt ( talk) 18:45, 25 April 2014 (UTC)

The section on "Buoyancy and movement" says, "To swim, the nautilus draws water into and out of the living chamber with its hyponome, which uses jet propulsion."
Could someone correct this? Jet propulsion only explains how it moves in the direction of the shell, squirting water out of the hyponome. The sections on Diet and Digestive system show that it has to bring its mouth to bear on food attached to rocks, which it cannot do by jet propulsion. Does the animal also move by suction, sucking water in, moving toward the tentacles? Does the animal pull itself towards its tentacles, by moving them on the bottom or in the water? That is the appearance in this video, but it might also be moving by suction: https://www.youtube.com/watch?v=vR6G-ANma1w Naturally the video is not a reliable source, but is there a reliable source on how it moves? The jet propulsion idea is conventional, but can only be part of the story. Numbersinstitute ( talk) 16:22, 16 January 2017 (UTC)
