Regulation and modulation of electric waveforms in gymnotiform electric fish [PDF]
Journal of Comparative Physiology A, 2006 Weakly electric gymnotiform fish specialize in the regulation and modulation of the action potentials that make up their multi-purpose electric signals. To produce communication signals, gymnotiform fish modulate the waveforms of their electric organ discharges (EODs) over timescales spanning ten orders of magnitude within the animal's life cycle ...

Convergent evolution of locomotor morphology but not performance in gymnotiform swimmers [PDF]
Journal of Evolutionary Biology, 2018 AbstractConvergent evolution of a novel locomotor strategy implies that a fitness benefit may be associated with the new gait. Opportunities to study this phenomenon are often constrained by a lack of transitional taxa, but teleost fishes offer examples of extant species across such evolutionary shifts in gait.

Sexual dimorphism in the electric knifefish, Gymnorhamphichthys rondoni (Rhamphichthyidae: Gymnotiformes) [PDF]
Acta Amazonica, 2019 Sexual dimorfism refers to morphological differences between males and females of a species. It may be a result of different selection pressures acting on either or both sexes and may occur in any sexually-reproducing dioecious species, including fishes.

Coding and processing of electrosensory information in gymnotiform fish [PDF]
Journal of Experimental Biology, 1989 ABSTRACT Studies of the electrosensory system of gymnotiform fish have revealed principles of neuronal coding and processing of information which also character-ize more advanced systems, such as vision and audition in higher vertebrates.
