Nautilus pompilius (aka, macromphalus, aka belairensis), the chambered or pearly nautilus is a member of the cephalopod class of the mollusks. The nautilus is a "living fossil" whose close relatives date back 100's of millions of years into geologic history. The life and habits of the nautilus are, for the most part, a mystery, although a great deal has been learned about the nautilus in recent decades.
