This scientifically accurate yet utterly charming field guide to the Pacific coast intertidal zone introduces readers to a world populated by spectacular wildlife.

Explore 150-year-old giant green anemones that paralyze their prey with their petal-like tentacles; sunflower sea stars that traverse the tide pool floor on twenty-four limbs; orange-tipped, opalescent sea slugs that dabble in cannibalism; and much, much more. Small enough to fit in a back pocket during a beach hike, this guide contains concise descriptions of tide pools' most common residents, noting each organism's size and zonation, as well as a few of its fascinating (and sometimes grotesque) habits. Full-color illustrations reminiscent of prints by Ernst Haeckel help tide poolers with easy identification, and tips for viewing help you explore the abundance that tide pools have to offer.
