Blue-waved chiton , Tonicella undocaerulea Photo by G. Fletcher

We frequently encounter this 4 cm. chiton while diving at Race Rocks. It occurs subtidal at 10 meters depth. It also occurs in the lower level tidepools as the photos above illustrate. These chitons strip off several species of calcareous encrusting algae from the rock substrate, They are equipped with a radula or rasp-ike tongue containing iron filings.
