We see here a rocky shore at Nahant, Massachusetts, where barnacles in a high intertidal site are found only in cracks. Barnacle larvae are known to select cracks over smooth rocks, but it is by no means clear that this is the only explanation for the pattern here.

Intertidal communities occur on sandy beaches, in bays and estuaries, and on wharf pilings, but the communities of rocky shorelines are perhaps the most diverse and the most densely populated. ... Rocky intertidal areas can be found all along the California coast; they are best observed at the lowest tides.

The plants and animals that live in the rocky intertidal habitat must be able to withstand pounding waves and when the tide is out, hours of dryness. The rocks create a fairly stable foundation for the seaweeds and animals that have evolved to depend on this seemingly harsh environment.

The rocky intertidal areas are an important interface between the sea and the land, providing habitat for numerous and diverse species in the Bay. Historically, impacts from wastewater discharges had a large impact on rocky intertidal areas in Southern California.
