Chiton

There are several species of chiton in southern California but the most abundant is the Southern Spiny Chiton (Nuttalina fluxa). Chitons are mollusks that can be identified by the eight interlocking shells that are held together by an oval of tissue referred to as the girdle. Unlike most chitons this species is not light sensitive and does not retreat under rocks or Rockweed during the day. Chitons feed on algae at night and often can be found in eroded pits (similar to Lottia home scars) during the day.
