Quick answers
Is an electric eel a true eel?
No. It is a gymnotiform knifefish. The body plan and voltage organ are South American, not Anguilliform.
How many species are there now?
A 2019 Nature Communications paper split Electrophorus into three: E. electricus, E. voltai and E. varii. Voltage and DNA both argued for the split.
How strong is the shock?
E. voltai has been measured near 860 V. That is a prey-stun and defence pulse, not a household-current analogy that holds in every tank.
What did Humboldt actually do in 1800?
His account of horses herded into a pool of eels became a European science anecdote. Later readers treated it as a method; it was also travel theatre.
Did electric eels inspire the battery?
Volta and Galvani debates used animal electricity. Electrophorus was a New World exhibit in that argument, not the sole inventor of the pile.
How do they hunt?
A high-voltage volley can freeze prey; a weaker field maps the night water. Kenneth Catania high-speed videos in the 2010s showed doublets that twitch hidden fish.
The electric eel did not enter English as a finished emblem. Hunts, films, listings and field stations rewrote the animal on a dated clock.
This chapter keeps ten timeline points, five eras and three milestones so a later translation can hold the same years.

Gymnotiform radiationAmazon and Orinoco basins
Timeline
1766Linnaeus Gymnotus electricus
The shock fish entered binomials from colonial specimens.
1800Humboldt horse episode
Travel narrative that locked the eel into European electricity lore.
1800Volta pile
The battery argument used animal electricity as a foil -- eels in the same conversation.
1880sSachs organ named
Anatomists mapped the stacked electrocyte columns that physics later modelled.
1950sKeynes / Nachmansohn era
Electrophysiology used the organ as a giant axon-adjacent preparation.
2014-16Catania hunt videos
Vanderbilt high-speed work showed remote twitch and double-pulse hunting.
2019Three-species split
de Santana et al. named E. voltai and E. varii beside E. electricus.
2019860 V note
E. voltai measurements reset the popular 600 V ceiling.
2021Dam-basin notes
Amazon hydropower papers began listing gymnotiforms among fragmented river fauna.
2023Pet-trade watch
Large Electrophorus still move as novelties; LC status is not a shipping brief.
The eras
1800s
Humboldt and Volta
A horse story and a pile put the eel inside electricity history.
1880s-1950s
Organ as prep
Anatomy then electrophysiology used stacked cells as a lab.
2014-19
Video and split
Catania hunts and a three-species paper rewrote the textbook singular.
2020s
Dams and tanks
Hydropower and the pet trade are the unromantic files.
Milestones
Humboldt narrative
1800A travel scene became the default European eel story.
Catania videos
2010sHunt kinematics moved from anecdote to milliseconds.
2019 split
2019One famous fish became three -- voltage included.
Reading electric eel history beside the resilience score keeps a recovered stock from standing in for a threatened cousin.
