		A relative of the octopus, squid and cuttlefish, the Chambered Nautilus is an ancient cephalopod.
		The Nautilus is the only living cephalopod to retain an external shell, today, the fossilized shells of extinct cephalopods provide a good record of their evolution.
		Nautilus shells such as this one we found in the waters surrounding the Vitu Islands, are left empty when the animal has died, they can be found floating at the surface of the sea or washed ashore.

		The Chambered Nautilus is the title and subject of a poem by (United States writer of humorous essays (1809-1894)) Oliver Wendell Holmes, in which he admires the "ship of pearl" and the "silent toil/That spread his lustrous coil/Still, as the spiral grew/He left the past year's dwelling for the new." He concludes with the peroration:

		The chambered nautilus is a cephalopod mollusc, most closely related to the cuttlefish, squid, and octopus.
		But, unlike snails, the nautilus shell is divided into compartments (about four in newly hatched specimens, 30 in mature individuals), and the animal occupies only the outer-most "living chamber." As the nautilus grows, its body moves forward in the enlarged shell and produces a wall to seal off older chambers.

		The animal lives in the largest and newest chamber, with a tubular elongation of the body, known as the siphuncle, extending through the septa to the apex of the shell.
		The nautilus breathes by means of two pairs of gills; it feeds on crabs and other animals, which it catches with its long, slender tentacles (numbering more than 90) that encircle the mouth.

	Chambered Nautilus (Site not responding. Last check: 2007-10-29)
		The shell of the nautilus looks similar to the shells of some snails, but the nautilus is a relative of squids and octopuses.
		Its shell is divided into chambers, and the animal always lives in the biggest chamber in the front.
		But the other chambers are also important because the nautilus uses them to control its buoyancy, and it either hovers close to the surface or goes deep down toward the bottom of the ocean.

		Most older textbooks suggest that while the chambered nautilus shell resembles the shells of extinct, dinosaur-era nautiloids, the living species are more recently evolved.
		One is composed of the king nautilus, which appears to have descended from the chambered nautilus about 15 million years ago; the other group is composed of everybody else.
		The long voyages of the nautilus, from the depths into the shallows each night, are thus a perfect metaphor for its evolutionary history, which comes up to our world unchanged from the great depths of time.

	On "The Paper Nautilus"
		The paper nautilus as both crab and hydra, keeps her young eggs from hatching too easily, lest in reaching their full size too quickly they are hindered to succeed, rather than hindered to succeed.
		Like the octopus, the nautilus has eight arms, and again like the octopus, the danger, although here a danger evaded, is that she will crush what she strives to protect, the precise risk that the glacier as octopus presents to what flourishes through and in her potentially devastating presence.
		Among these texts, her "Paper Nautilus" is a central statement (121-22), a text that offers the maternal as a kind of reproduction different from mimicry, as a version of both creation and procreation with reference not to woman's body but to diverse forms of spatial representation.

		The eggs were maintained in separate incubator tanks at a constant temperature of 22º C (72º F), corresponding to the water temperature in the shallower depths visited by the adult nautilus at night.
		This "guess" at the correct incubator temperature resulted in the discovery of the first nautilus embryos known to science in 1985.

		The older closed chambers of the shell contain an argon-nitrogen gas mixture and a liquid saline solution.
		The chambers are connected by a tube called a sipuncle that gives the nautilus the ability to change the ratio of liquid to gas which modifies its weight.
		The nautilus moves in a see-saw motion using "jet propulsion" by alternately pulling water into the mantle cavity within the shell and blowing it out the muscular, flexible siphon (funnel) beneath the tentacles.

		The nautilus was one of these, and many an idle sailor would spot this tiny shelled creature floating on the quiet sea.
		The nautilus is "a small dibranchiate cephalopod, the female of which is protected by a very thin, single-chambered, detached shell, and has webbed dorsal arms" - "purpled wings" formerly believed to be used to catch the wind and drive the nautilus along.
