Nautilus macromphalus
Nautilus macromphalus are invertebrates species that are apart of the mollusca phylum, which is one of the largest phylum of invertebrate animals. They are one of 6 species of the Nautilus genus. Two of those species are currently extinct. Nautilus macromphalus are also known as the belly button nautilus. The Nautilus macromphalus originates from Australia. N. macromphalus can be found in open marine waters surrounding the Loyalty islands. The chambers of the Nautilus macromphalus are formed when the previous chamber is almost emptied of cameral fluid. There are also other ways in which the chamber of the Nautilus macromphalus can form without emptying the fluid from the previous chamber. The chamber of the Nautilus macromphalus is responsible for its buoyancy in the water. If the Nautilus macromphalus grows without emptying fluid in the chamber, the mollusk will be too heavy to remain buoyancy. Ajtomlin (talk) 03:58:27 February 2019 (UTC)

Evolution of the Chambered Shell
The formation of the chambered shell of N. macromphalus includes mural ridge formation, secretion of the siphuncular connecting ring, septal calcification, and cameral liquid removal. The formation of the chambered shell begins with the removal of over half of the cameral liquid that was created in the last chambered formation. Next, the liquid in the chamber drops from direct contact with the permeable connecting ring. It, then, moves onto the siphuncular connecting ring because of the properties of septal face and neck. This change coexists with the formation of mural ridge. It has been proven that it takes a significantly longer time for the formation of the chambered shell than the shell formed before it. The rate of apertural growth of N. macromphalus, which is the growth of the opening, is decreased by increasing shell breakage at the aperture. The rate of chamber formation is also decreased by increasing shell breakage.

Reproduction
Like many other invertebrates, Nautilus macromphalus has an interesting way of depositing eggs. The eggs of Nautilus macromphalus are different. For instance, their eggs are enclosed in a special casing. The ovum of Nautilus macromphalus are confined in between two capsules, making the enclosure a double casing. The enclosed eggs can grow up to 45 mm in length, 16 mm in width, and 16.25 mm in height. No two eggs look the same. The males of Nautilus macromphalus carries a spermatophore in the cephalic region. It is confirmed that reproduction of Nautilus macromphalus takes place all throughout the year.

Legislation of Nautilus
In September of 2016, the United States, Fiji, India, and Palau submitted a proposal to protect these species at the 17th Conference of the Parties of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The proposal was created to avoid over-exploitation of the species and other species in the Nautilidae family. Intrinsic biological traits, as well as extrinsic threats, make Nautilus macromphalus very vulnerable to over-exploitation. As of January 2, 2017, Nautilus macromphalus are protected under Appendix II of CITES. 98.101.237.40 (talk) 23:26, 13 April 2019 (UTC)

peer edit: This is a great start! The species name needs to be italicized and I think the material is great but it might need to be broken up into different sections! overall it was very informative. — Preceding unsigned comment added by Sk10001 (talk • contribs) 03:58, 6 March 2019 (UTC)
