I have purchased other amphibian books that have far more pictures and maps. This has no maps of the area, so one would expect that all amphibians and reptiles in the book are found everywhere in the area. I know that is not true from other reptile books. "A Field Guide to the Amphibians and Reptiles of the Maya World: The Lowlands of Mexico, Northern Guatemala, and Belize" by Julian C. Lee is far superior and we've been able to identify every species we have seen. The maps are better in Lee's book and the images are larger and more clear. I can't see why this book recieved 4.5 starts as it is basically useless for identification.
