University of Florida. (2006, February 6). Scientists Trace Origin Of Shark's Electric Sense. ScienceDaily Citat: "..."Sharks have a network of electrosensory cells that allows them to hunt by detecting electrical signals generated by prey," said Martin Cohn, a developmental biologist with the departments of zoology and anatomy and cell biology, and the UF Genetics Institute. "That doesn't mean they can only detect electric fish. They can sense electricity generated by a muscle twitch, even if it's the weak signal of a flounder buried under sand."..."
Washington University in St. Louis. (2015, August 4). Fish that have their own fish finders. ScienceDaily Citat: "...The fish with nuanced signal discrimination can glean a stunning amount of information from electric signals, including the signaler's species, sex, age, relative dominance status, and possibly even individual identity. They can also detect emotional states, such as aggression, submission, courtship and active exploration. The fish with the simpler communication system were less studied and less well understood..."
