2. Electric eel - Wikipedia

   en.wikipedia.org/wiki/Electric_eel

   The electric eels are a genus, Electrophorus, of neotropical freshwater fish from South America in the family Gymnotidae. They are known for their ability to stun their prey by generating electricity, delivering shocks at up to 860 volts. Their electrical capabilities were first studied in 1775, contributing to the invention in 1800 of the ...

3. Picana - Wikipedia

   en.wikipedia.org/wiki/Picana

   Description and use. The picana is a wand or prod that delivers a high voltage but low current electric shock to a torture victim. It has a bronze tip and an insulated handle, and is connected by wire to a control box with a rheostat to raise or reduce the voltage. Power is supplied by a car battery or by a transformer connected to a mains wall ...

4. Electrofishing - Wikipedia

   en.wikipedia.org/wiki/Electrofishing

   Electrofishing. Scientists carrying out a population and species survey using electrofishing equipment. Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.

5. Electric fish - Wikipedia

   en.wikipedia.org/wiki/Electric_fish

   An electric fish is any fish that can generate electric fields, whether to sense things around them, for defence, or to stun prey. Most fish able to produce shocks are also electroreceptive, meaning that they can sense electric fields. The only exception is the stargazer family (Uranoscopidae). Electric fish, although a small minority of all ...

6. Electric catfish - Wikipedia

   en.wikipedia.org/wiki/Electric_catfish

   Malapterurus. Paradoxoglanis. Electric catfish or Malapteruridae is a family of catfishes (order Siluriformes). This family includes two genera, Malapterurus and Paradoxoglanis, with 21 species. [1] Several species of this family have the ability to generate electricity, delivering a shock of up to 350 volts from its electric organ. [2]

7. History of bioelectricity - Wikipedia

   en.wikipedia.org/wiki/History_of_bioelectricity

   History of bioelectricity. The history of bioelectricity dates back to ancient Egypt, where the shocks delivered by the electric catfish were used medicinally. In the 18th century, the abilities of the torpedo ray and the electric eel were investigated by scientists including Hugh Williamson and John Walsh.
