shell2Univalves reveal a spiral design that has fascinated artists, biologists and mathematicians throughout the ages.  The mathematical equation on which the proportions of this design are based is known as the Golden Mean, Golden Section and the Golden Ratio. 

Although the most excellent example of this ratio is the shell of the Chambered Nautilus, the spirals found in these simple freshwater shells also aspire to similar proportions.

These drawings were made with colored pencils.
