Like other chitons, it is a slow moving grazer that consumes several species of brown and red algae including kelps, sea lettuce, and encrusting diatoms. They're also known to eat sponges, tiny barnacles, spirobid polychaetes, and bryozoans. Their predators include sea urchins, leather stars, black oystercatchers, glaucous-winged gulls, and humans.(Wikipedia).
