Seashell whorls
A whorl is a single, complete 360° revolution or turn in the spiral growth on a seashell. This shell has several whorls but my photograph concentrates on those in the centre where the shell's growth began. Incidentally, the dominant line of the shell is a true spiral. In everyday use the helix (as seen in a traditional metal spring or the spiral staircase ) is often called a spiral.
