This comprehensive, easy-to-follow, full-colour guide introduces more than 250 species of mollusks -- the clams, oysters, scallops, mussels, abalone, snails, limpets, tuskshells and chitons found along the beaches and intertidal and shallow waters of the Pacific Northwest. Detailed descriptions and colour photographs help identify each species -- many of them photographed in their natural settings -- and the guide is packed with info on habitat, biology, and shell and body features, as well as the importance of single- and two-shelled mollusks to Northwest Coast aboriginal culture. A special full-colour section on identifying clams by their siphons or "shows" is a first for shell guidebooks. Checklists, edibility guidelines, notes on conservation and tips for collectors round out the guide. Whether you're a diver, a wildlife enthusiast, a serious collector or just a weekend beachcomber, you won't want to go to the beach without this one!
