Written by Jesús Rivas, the undisputed expert on the biology of anacondas, this is the first authoritative book on the biology of the green anaconda, the world’s largest snake. Rivas describes his experiences over a quarter of a century exploring the secret life of these fantastic snakes, including their diet, movement patterns, life and tribulations, survival, behavior, and fascinating reproductive life. But more than just presenting facts about anacondas, Rivas tells his story about studying them in the field. Ultimately, his love for anacondas and his unorthodox approach give his voice a unique accent that makes this book stand out among other books of its kind. The rich photography and its storytelling approach make this an enjoyable and thoroughly readable book that can sit as comfortably on a coffee table as in the bookshelves of advanced scholars.
