The chambered nautilus, Nautilus pompilius also called pearly nautilus, is the best-known species of nautilus.The shell, when cut away, reveals a lining of lustrous nacre and displays a nearly perfect equiangular spiral, although it is not a golden spiral.he eyes of the chambered nautilus are more primitive than those of some other cephalopods; the eye has no lens and thus is comparable to a pinhole camera.
Habitat. The chambered nautilus lives in tropical waters extending from the Andaman Sea east to Fiji and from southern Japan to the Great Barrier Reef.This animal usually lives where the slopes of coral reefs descend into deep waters.During the day, it resides in dark cool waters at depths from 900 to 2,000 feet and ascends to shallower waters (300 to 500 feet deep) at night to feed.he nautilus's graceful shell has made it an attractive commodity for the commercial shell trade, and Nautilus pompilius is the most commonly sold species. Traders from Indonesia, Fiji, and the Philippines capture nautiluses using baited traps.
