Theory of Electric and Magnetic Orientation in Sharks and Rays Revisited

The book describes the theory of electromagnetic orientation in sharks and rays.  The theory evolved from studying the publications of Faraday, von Arx, and Longuett-Higgins. Sharks and rays can detect the earth’s magnetic field as well as the ambient electric fields, utilizing their electrosensory system, the Ampullae of Lorenzini. Dr. Kalmijn provides the physical description of this sensory sys...
