Electronic Warfare - By Fish!

According to a new item in Science News, the modern combat tactic of jamming a rival's sensors is not so modern. Fish do it! The 15-cm brown ghost knifefish (Apteronotus leptorhynchus), which uses an electric field for detection and communication, can change the frequency of its field to jam that of a nearly rival. Simply amazing.
