nautilus shell
Chambered marine exoskeleton
A nautilus shell is the spiral, chambered shell of the nautilus, a marine mollusk.
The shell's geometry—each chamber proportionally larger than the last—makes it a visual symbol of mathematical harmony and natural design.
The creature lives only in the outermost chamber, sealing off earlier ones as it grows: The nautilus shell on her shelf was her favorite beach find.
