Zigzags and blotches


Lined Chiton (Tonicella lineata) with coralline algae.  Photographed near Mendocino, CA, 28 October 2012

While the eye-catching zigzag markings are distinctive in this species, the dark maroon blotches are variable.  I don't recall reading anything about why some individuals have blotches and others don't.  Any ideas?
