Although this book was written primarily as a guide for divers the quality of the photos and the complete descriptions of the marine invertebrates found in the book make it a great reference work. There is a sizable part of the book covering the mollusca. All the major classes are covered and the greatest number of them are the Opisthobranchs. All the animals covered in this book are photographed live in their habitats and the photos are of outstanding quality.
