This book follows the same format as the Encyclopedia of Marine Gastropods. Encyclopedia of Marine Bivalves, Including Scaphopods, Polyplacophora and Cephalopods illustrates in color more than 2000 species of marine molluscs and contains more than 5000 photos to help with the identification of color forms. There is almost no text, the key beneath each plate provides minimal information about the shells and lets the pictures do the talking.
