This book has good clear pictures but very little written information about each picture.
Does not contain more than photos and a small text box per creature. There is no mention of sizes, something of great importance when stocking an aquarium. For me, it is too quick of a reference quide. The information (and much beyond that) contained here can be found in Nilsen's "Reef Secrets".
Good reference text, pity about poor packaging

This is a wonderful first reference text from Julian Sprung. Well set out and communicates the necessary information in an undestandable way. A word of advice, don't get this text in a hardcover version as the pages are poorly bound and Amazon's inability to adequate package the book results in damaged corners. Why pay more to get damaged goods and the Amazon run-around?
Invertebrates: A Quick Reference Guide

After 30+ years as a salt water enthusiast, I can easily say thAt this book answers the majority of questions about the proper ways to keep inverts alive and well in a home aquarium setting.
I highly recommend this book-it will save you frustration and money! In addition, the numerous photos will aid you in identification and also your decision making for invert purchases.
BUY IT!
