Research Topics

Electroreception in Fishes


African snoutfish (Mormyriformes) and South American knifefish (Gymnotiformes) communicate and locate objects and obstacles with their electric system, consisting of a system for sending signals (electric organ discharges) and receiving them (electroreceptor organs). The electric organ discharges are species-specific, under sexual selection and play a role in mate quality assessment. Electric organ discharges are a useful tool in taxonomic-systematic research in these speciose fish groups.
