The Chambered Nautilus Sea Shell



Chambered Nautilus, 

Nautilus pompilius Linneaus.

The Chambered Nautilus is a relative of the octopus-squid family and serves as a true  protective home for its occupant. The Nautilus shell  is a creamy white with brownish stripes and the interior has a beautiful lustrous mother-of-pearl finish. The shell is structured with several gas-filled chambers which increase in number as the animal grows. The shells' resident is a member of the Cephalopods family and lives in the last chamber of the shell. Each segment of the shell is linked to adjacent chambers by a pore or sphinucle which regulates the gas flow within the chambers permitting the animal to dive to great depths without the extreme water pressure breaking  the  shells structure.
