"At the edge of the Pacific Ocean, where land and sea meet, lies a narrow strip of beach called the intertidal zone. A remarkable community of hardy shoreline creatures flourishes in this environment of ever-changing conditions. In this third book in the West Coast Wild series, readers will meet brightly colored sea stars, a giant Pacific octopus, busy hermit crabs, delicate sand dollars, fish that camouflage, and other intriguing marine animals that a child might see on a beach walk at low tide"--,Provided by publisher.
