Twan Leenders is President of the Roger Tory Peterson Institute of Natural History in Jamestown, New York, and author of Amphibians of Costa Rica.
Overall the book is an amazing accomplishment— scientifically sound, beautifully constructed, and artistically orchestrated. The photos alone are reason enough to collect the book for your library. The guide is absolutely necessary for reptile exploration in Costa Rica. * Sonoran Herpetologist *
