Explore the wild shoreline of the majestic Pacific west coast and discover the spectacular array of colorful creatures living in rhythm with the tides. At the edge of the Pacific Ocean, where land and sea meet, lies a narrow strip of beach called the intertidal zone. Endless tides move back and forth across the zone twice a day. A remarkable community of hardy shoreline creatures flourishes in this environment of ever-changing conditions. 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.
