Dead Sea Seashells, Segment E, part 6 of 6

A small group of spiral seashells

 

The final portion of our collection of seashells found on the shores of the Dead Sea, is the collection of nautilus shells. These shells are made by mollusks in the cephalopod class.. Cephalopods include squids and octopuses, and nautilus are the only cephalods whose external shell is the only manifestation of bony structure. They can retreat entirely into their shell.
