Neurobiology, Utrecht University, Padualaan 8, 3584 CH Utrecht, Th e Netherlands Abstract A large range of aquatic vertebrates employs passive electroreception to detect the weak bioelectric fi elds that surround their prey. Bioelectric fi elds are dynamic in strength and frequency composition, but typically
