I own 3 copies of the book (two of the second edition, one of the first) because I would fear the day that they would stop printing it. As an avid diver, research scientist, and conservation biologist, I am frequently diving around the world such as in Belize, Honduras, Panama, St. Lucia, Madagascar, Egypt, Sulawesi, Maldives, among other sites. I have never found a better or more accurate field guide as the ones that they have prepared that is useful in all of these sites, and provides such stunning and accurate illustrations that allow for easy identifications of very similar species. I strongly recommend buying this book!
