FIGURE 13.7 Intertidal zone. Organisms that live in the area between high and low tide, such as these giant green sea anemones (Anthopleura xanthogrammica), goose barnacles (Lepas anserifera), and ochre sea stars (Pisaster ochraceus), must be highly tolerant of the harsh, desiccating conditions that occur during low tide. This photo was taken at Olympic National Park, Washington.
