Two Clinical Records of Human Injuries with a Death caused by Electric Eels Electrophorus spp. Gill, 1864 [PDF]

Revista da Sociedade Brasileira de Medicina Tropical
Electrical eels, or poraqués or temblones (Electrophorus spp. Gill, 1864), are highly feared animals in the Amazon, mainly because of their electric discharge of up to 860 volts. We report two cases of human injuries caused by electric eels, one of which

In Vitro Evaluation of Neutral Aryloximes as Reactivators for Electrophorus eel Acetylcholinesterase Inhibited by Paraoxon [PDF]

Biomolecules, 2019
Casualties caused by organophosphorus pesticides are a burden for health systems in developing and poor countries. Such compounds are potent acetylcholinesterase irreversible inhibitors, and share the toxic profile with nerve agents.

A chromosome-level genome assembly of Electrophorus voltai, a species of electric eel [PDF]

Scientific Data
Electrophorus voltai, a South American electric eel, is renowned as the most powerful bioelectricity generator, capable of producing electric discharges reaching 860 volts. This remarkable ability positions it as an invaluable model for investigating the

Organization of the cephalic lateral-line canals in Electrophorus varii de Santana, Wosiacki, Crampton, Sabaj, Dillman, Mendes-Júnior & Castro e Castro, 2019 (Gymnotiformes: Gymnotidae)

Neotropical Ichthyology, 2021
Electrophorus spp. generate high-voltage electric discharges for defense and hunting, and low-voltage electric discharges (as other Gymnotiformes) for electrolocation and communication.

Feeding ecology of electric eel Electrophorus varii (Gymnotiformes: Gymnotidae) in the Curiaú River Basin, Eastern Amazon [PDF]

Neotropical Ichthyology, 2020
In this study, the composition of the diet and the feeding activity of Electrophorus varii were evaluated. The influence of ontogeny and seasonality in these feeding parameters was also examined.

Theileria electrophorin.sp., a parasite of the electric eel Electrophorus electricus (Osteichthyes: Cypriniformes: Gymnotidae) from Amazonian Brazil [PDF]

Memorias do Instituto Oswaldo Cruz, 2007
The name Theileria electrophori n.sp. is proposed for a small parasite described in the erythrocytes of the electric eel, Electrophorus electricus, from Amazonian Brazil. Division of the organism in the erythrocyte produces only four bacilliform daughter
