Take a closer look into the secret worlds of the intertidal zone

A spectacular variety of life flourishes between the ebb and flow of high and low tide. Anemones talk to each other through chemical signaling, clingfish grip rocks and resist the surging tide, and bioluminescent dinoflagellates—single-celled algae—light up disturbances in the shallow water like glowing fingerprints.

This guidebook helps readers uncover the hidden workings of the natural world of the shoreline. Richly illustrated and accessibly written, Between the Tides in Washington and Oregon illuminates the scientific forces that shape the diversity of life at each beach and tidepool—perfect for beachgoers who want to know why.

• profiles of popular and off-the-beaten-track sites to visit along the Greater Salish Sea, Puget Sound, and Washington and Oregon coasts
