Field Notes
Description:
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.
Habitat:
Cabrillo National Monument
The park offers a superb view of San Diegos harbor and skyline. At the highest point of the park stands the Old Point Loma Lighthouse, which has been a San Diego icon since 1854. A statue and museum in the Visitor Center commemorate Juan Rodrguez Cabrillo's exploration of the coast of California. In a former army building an exhibit tells the story of the coast artillery on Point Loma.
In the winter, migrating gray whales can be seen off the coast.
The two-mile Bayside Trail affords spectacular views of San Diego Bay and the city beyond, and takes you through one of the last remaining remnants of coastal sage scrub habitat in the world.
The rocky intertidal area is one of the best protected examples of these unique ecosystems in Southern California.
