摘要：

Natural selection by predation is often viewed as a constraining force on the signals used by animals: the more conspicuous a signal, the more risky it is. But both correlational and experimental evidence from weakly electric fish seem to show that, in this case at least, predation has in fact been a creative force and resulted in more elaborate signals than would otherwise have been the case.
