Thanks for posting the links to your report. Your pictures are outstanding and the herp species list is impressive! I especially like the "animal in its habitat" wide angle shots like Corallus caninus, Eunectes murinus. I'm amazed how many snakes you have been able to find. It looks that you got very suitable weather conditions. This must have been a completely different kind of trip than our Guyanan adventure last year.
How safe is French Guyana? Did you ever feel unsafe in the coastal area? I'm asking this because coastal "ex British" Guyana is told to be a dangerous place for (the few) tourists. Being aware of this fact, we dared to do a short walk in Georgetown during daytime. My camera got robbed within an our by a local (showing me his knife that he would undoubtedly have been using if I tired to get the camera back...).
