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.
Now, scientists say, humans are loving the chambered nautilus to death, throwing its very existence into danger. âA horrendous slaughter is going on out here,â said Peter D. Ward, a biologist from the University of Washington, during a recent census of the marine creature in the Philippines. âTheyâre nearly wiped out.â.
