The “Philippine Marine Mollusks” volumes are setting the modern standards for Marine Indo Pacific Mollusks in general. They are a summary of the confirmed knowledge on Philippine marine mollusks and cover all groups of mollusks, including nudibranches. The books cover over 3600 species and count about 10000 photographs on approximately 1315 color plates in A4 format. Hundreds of species are shown alive with underwater photographs.

This volume covers all families from the Patellogastropoda down to the Cerithiopsidae. A short bibliography and a practical index close the Volume I.
