The Marine Atlas Volume 3 begins on page 737, an indication that Volumes 2 and 3 are parts of a single unit of 1,322 pages. Beside its photographs and accompanying information, this book contains a glossary and a comprehensive index for both volumes. Both the publisher and the authors are proud of the amount of information they could pass to their readers. Hopefully, interested aquarists will be able to translate the information into better care for their captive marine invertebrates.This volume covers invertebrates: sponges, worms, starfish, jellyfish, giant clams, urchins and MUCH, MUCH MORE. Some readers will find information among these pages that will enhance and diversify their knowledge. Softcover.
