Electrocommunication in Teleost Fishes. Behavior and Experiments. B. Kramer. Springer Verlag, Berlin, Heidelberg, New York, London, Paris, Tokyo, Hong Kong, 1990, ISBN 3-540-51927-0, DM 198.00 hardcover. This comprehensive monograph (Contents: (1) Taxonomy of Electroreceptive Teleosts, (2) Electric Sensoric-motor Systems, (3) Species Diversity of Electric Organ Discharge Activity, and (4) Communicating with Electric Organ Discharges.) describes in detail not only the morphological properties of all species of “electric fishes” including evolution of their organs (Chapters 1 and 2), but analyzes extensively the bioelectrochemical functions of discharges (“animal electricity” in the definition of L. Galvani) and reception (Chapter 3) also for electrocommunication (Chapter 4) between such fishes. Basic wave forms and trains of short low pulses (about 1 ms duration; lo-100 Hz repetition on the one hand and single high pulses (about 500 V) on the other hand from the electric-organ discharges of such fishes, mostly from Africa and South America, were analyzed carefully and shown in more than 30 diagrams. Surprising signals of the social behavior between male and female specimens or during fights between different species were recorded including learning experiments. The ability to discriminate between signals and the sensitivity of responses (in the order of microvolts) is amazing, enabling the fishes to communicate in their nocturnal life. This book is an up-to-date account, providing more than 300 references and a deep insight into sophisticated sensory perceptions which we humans miss. D. MANGOLDT Berlin
