Identify marine life of the Pacific Coast—from Alaska to Baja California—with this pocket-size guide. The booklet begins with introductions to intertidal zones, intertidal species, and tidepools, followed by brief discussions of important aspects of intertidal life, such as water temperature and food. A field guide section presents more than 90 species of marine life, organized by groups such as algae, crabs, mussels, sea stars, and sponges. Simply answer a series of simple questions about the shape and appearance of an organism. Your answers lead to the correct section, where you can compare what you’ve found with the species shown. Professional illustrations by Pam Frazier and visual descriptions help you to identify each species. This guide is applicable to the rocky reefs and tidepools of the Pacific Coast in Alaska, Baja California, British Columbia, California, Oregon, and Washington. [64 pages]
