Update (February 2014): Following the passing away of the author this book has now gone out of print, and will not be reprinted. In December 2013 Chimaira published The Complete Oophaga pumilio, which presents a good alternative.
This colour morph guide presents 102 different colour forms and locations of Oophaga pumilio. All profits go to the Panama Pumilio Protection Project to protect these poisonous frogs.
