It is available online for free, and there is one edition in English, and another in French.
You will find a number of other informative publications on a variety of reef topics as well at this web page, all free to download.
There is also a printed version of the crustacean guide which has both languages, not sure how to get that, best to contact CRISP.
The photos are gorgeous, and the text informative, it covers 223 species. There is a section of general information on crustaceans at the beginning of the book. The book covers reef, shore, mangrove, stream, and terrestrial species.
