Abstract:

Two areas along the intertidal terrace at Santa Cruz, California, were surveyed for rock boring bivalves. At one location, all associated macroscopic epibenthic fauna and flora were identified and quantified. Rock samples were collected representing all rock types where borers were found. Results showed that Penitella penita was the most abundant rock borer in both locations, being found to heights of 2 meters above MLLW. The next most common borers were two species of Adula. Rock analysis showed that 32 out of 34 samples had calcium carbonate content less than 0.8 by weight, thereby indicating that in these locations the boring mechanism is probably not chemical. Author
