Electric fish court each other by coordinated electronic "singing"....
Cornell researchers have discovered that in the battle of the sexes, African electric fish couples not only use specific electrical signals to court but also engage in a sort of dueling "electric duet."
The study is the first to compare electrical and behavioral displays in breeding and nonbreeding Brienomyrus brachyistius, a type of mormyrid electric fish, which emit weak electric fields from a batterylike organ in their tails to sense their surroundings and communicate their species, sex and social status with other fish.
