I had 3 years of French in high school and college and I can read most of it, although slowly. You'll quickly pick up some of the description-related words, such as "tache" (spots). Most of the biological words are similar to English or you can figure them out from context, for example "14 sillons costaux" = 14 costal grooves. A lot of scientific words are similar in all languages, and the text is written fairly simply.
The best way to order it from the US is probably to contact Jean Raffaelli directly. I think he gave his email address in one of the posts on this thread.
i highly recommend “buyanaxolotl.com”- ive purchased from them and received a beautiful animal for relatively cheap, in great condition, and excellent shipping precautions. the breeders are a couple living in georgia (i believe, don’t quite remember) and they’re fantastic. sometimes their website contact page doesn’t work, so i’d probably try just emailing them. good luck and happy hunting!
