More tolerant of light than many other chitons, and can be seen out in the open on foggy days on the Pacific Coast of North America. It spends most of the daylight hours under rocks, however, and moves primarily at night when the animal is wet or submerged. Individuals that are exposed at low tide show homing behavior, moving within a radius of roughly 19.6 in (50 cm) from home base, frequently returning by a set pathway to original resting place when immersed by tide. Individual home ranges do not overlap, but chitons living in tidepools (which are never exposed) do not appear to maintain home ranges.
