Appropriate for the collector, budding naturalist, or diver, this book uses drawings and underwater photos to describe the anatomy and behavior of each shell's inhabitant, then provides a geography of marine mollusks. Finally, the author shares some tips from his monthly column about shell collecting, including what to wear, how to clean and display shells, and what information to record (he includes a sample record from a database). An identification guide with lovely drawings concludes the work. Annotation c. Book News, Inc., Portland, OR (booknews.com)
