The new biological reference

As scuba divers + organic, this book fills all my expectations! It goes directly into the top of the underwater biological references. It is also well designed for experienced divers and beginners. Species are described in the introduction to each chapter using diagrams. It includes for each branch as well as the Latin name and common name names used in all languages. The fish portion is also reduced, which gives way to the species more "small" (nudibranch, mollusks, crustaceans ...). For fish prefer the book of Patrick Louisy.
In short: if you do only one mediterranean biology book, choose it without hesitation.
