Electric Courtship

An African electric fish, Brienomyrus brachyistius, uses its weak electric signals in courtship behavior. From the research news:

"The research, which is the cover story in the July 1 issue of the Journal of Experimental Biology, is authored by Carl D. Hopkins, Cornell professor of neurobiology and behavior, and Ryan Wong '05, who conducted the study as an undergraduate for his senior honors thesis and is now a Ph.D. student at the University of Texas in Austin.
'"Our study provides strong evidence that the "rasp" [a certain electric signal] is a male advertisement call during courtship in this species,' said Wong, noting that the males also serenade females with lower frequency 'creaks.'"
