Caption Amplified electric pulses were recorded at Biroudou Creek in southeastern Gabon. Each click represents a single electric-organ discharge, which is about one millisecond long. Several fish can be heard in this recording. A fish's signal becomes louder when it moves closer to the electrode picking up the discharges.
