All the information needed to collect and study shells is included in this comprehensive book, which provides the geographical range and habitat for and a detailed description of each of 800 species. Color plates show 780 species, including live animals, and 115 drawings show both animals and their shells.
This is a book you have to keep around for multiple references. There is way too much info to memorize! The pictures are good for identifying. I did learn some new things by looking through it.
