The widespread appearance of frogs with deformed bodies raises an alarming question about the health of aquatic ecosystems and potential human impact. Michael Lannoo, drawing on expertise from ecology, parasitology, and other disciplines, investigates the causes behind these malformations, identifying affected frog species and considering the implications for human populations. The book synthesizes data to explore potential causes, with a particular focus on chemical, nutrient, and pesticide runoff into wetlands as key factors. Lannoo advocates for practical solutions to address this disturbing environmental problem.

This book is regarded as a comprehensive and authoritative reference on the phenomenon of frog deformities. Experts and readers alike have noted its thorough scientific approach, integrating data from multiple disciplines to provide a balanced overview. The inclusion of detailed radiographic images and the focus on practical solutions are frequently highlighted as valuable contributions. The work is considered essential for understanding the environmental factors contributing to amphibian malformations and their broader ecological significance.
