The binding is great.  The full-page color photos are fabulous.  But the information is a bit shallow and rather strangely organized.  Each page offers two to three sentences about a different animal that happens to be green.  There’s no real consistency about the type of information offered on each animal.  It doesn’t specifically focus on how their greenness is significant, though a sentence in the back of the book does state that mostly green is used for camouflage.
