Tube-snouted gymnotiform and mormyriform fishes: convergence of a specialized foraging mode in teleosts

African mormyriform and South American gynmotiform fishes are unique among freshwater fishes in their abilities to generate and perceive an electrical field that aids in orientation, prey detection, and communication. Here we present evidence from comparative ecology and morphology that tube-snouted electric fishes of the generaSternarchorhynchus… (More)
