Electric fish produce electric signals for navigation, prey location, and communication. These signals vary widely among species, but the forces that have led to this diversity remain unclear. Predation has been proposed as a potential evolutionary force shaping electric fish signals, but this has not been tested in the field. The purpose of this thesis is to explore the ways in which predators affect electric fish signals. In the first chapter, we provide field evidence supporting the hypothesis that predators are driving the evolution of electric fish signals. In the second chapter, we explore the more acute effects of predation. Caudal injuries are frequently observed in some electric fish, presumably as the result of sublethal encounter...
