"The book is divided into four parts: biosonar, biological compasses, electroreception, and the scents of attraction. Although it is filled with fascinating descriptions of animal sensitivities - the sonar system of a bat, for example, rivals that of the most sophisticated human-made devices - the author's goal is to explain the anatomical and physiological principles that underlie them. Knowledge of these mechanisms has practical applications in areas as diverse as marine navigation, biomedical sciences, and nontoxic pest control. It can also help us to obtain a deeper understanding of more familiar sensory systems and the brain in general."--Jacket.
