Mopalia lignosa , the woody chiton, can also be colorful.   Valve colors include gray-brown, bluish, or green with feathery markings.   Additionally, rows of pits may be seen on the valves.   The narrow girdle may be cream, brown, or purple brown with light spots from which sprout soft hairs.   The woody chiton grows to a length of about 3 inches and is found on the sides or undersides of boulders.   It feeds primarily on Ulva (sea lettuce).
