Question

Quizplus · Accepted Answer

The rocky intertidal zone is an area that is exposed to air at low tide and submerged by seawater at high tide. The low-water portion is the area that is usually only exposed during the lowest tides. This portion of the rocky intertidal zone is dominated by red and brown algae and surf grasses, which are adapted to withstand the drying out and exposure to sunlight that occurs during low tide. The other options, including hermit crabs, fiddler crabs, limpets, and mussels, are more commonly found in other intertidal zones such as the mid-tide or high-tide zones.
