“For 250 years, scientists thought the electric eel was a singular species and completely alone in its genus.”

Known as the “numb fish” in some parts of the world, the electric eel isn’t a true eel. This freshwater fish resides predominantly in the Amazon, even though the larvae float to New Zealand as they hatch. The bony body of the fish keeps it from offering much meat in eclectic dishes, but their exclusivity creates high demand.



Along the bottom of their body, the eel has multiple organs to set off each electric shock when they need to attack in the water.

5 Incredible Electric Eel Facts!

Here are a few facts about the electric eel:

• The diet of an electric eel is carnivorous, using their shock to attack any prey.
• Their total length can be more than 8 feet long.
• They prefer areas with fresh and murky water, though the rising water levels in rivers in South America can put them at risk for attack by land mammals.
• Though most “fun facts” lists categorize the electric eel with other eels, they are closer in their genetics to carp and catfish.
• This species is nocturnal with terrible eyesight.

Classification and Scientific name

The scientific name of this species is Electrophorus Electricus. They are known by a few different names around the world, including “arimna” and “numb eel,” though these names are specific to Venezuela and Europe (respectively).



From the order Gymnotiformes, the electric eel is part of the Gymnotidae family in the Actinopterygii class. Currently, there are three types of electric eels.



The scientific name is relatively straightforward in its meaning. “Electrophorus” comes from the Greek words ήλεκτρον (“electron”) and ϕέρω (“phero”), literally translating to “electricity bearer.” “Electricus” is a Latin word, which comes from the word “amber,” due to the substance that gets rubbed together to cause electrostatic energy.

Electric Eel Appearance

Typically growing to a length of 8 feet or more, the electric eel varies in size until it is an adult, eventually reaching about 45 pounds. Found in warm and murky waters, this fish has scaleless skin, making it smooth and almost slimy with a snake-like figure. Their back and sides feature dark gray to grown, which is why they hide so well in darker waters. Their belly is typically yellow to orange.



The organs that set off the electric shock – the main electrical organ, Hunter’s organ, and the Sachs’ organ – are responsible for producing 1+ amps. Each attack releases 1+ amps, which is why there are no consistent predators. After all, one or two amps alone are enough to induce a severely painful shock.

Distribution, Population, and Habitat

Where to Find Electric Eels and How to Catch Them

The natural habitat of the electric eel is exclusively freshwater areas, even though they prefer murky pools. These habitats are easily found in South America, though they are primarily found in middle and lower Amazon and Orinoco river basins. Though it can live in many water depths, they reach the surface to breathe the air because of the anoxic waters.



Currently, the electric eel is not endangered, so no conservation efforts are being made. Locals are encouraged to stay away from them and not capture them to protect the area from infestations.

Predators and Prey

This species is carnivorous, going after other animals as their prey. They hunt in the waters they live in, using the electric current along the length of their underside to attack their target.

What eats electric eels?

Apart from being fished by humans, electric eels have no known predators. They are too dangerous for other species to go after, regardless of water levels. If the water is shallow, there’s a chance that large land mammals will go after them, but this threat is often deterred with a shock.

What do electric eels eat?

Electric eels have quite a selection available to them in South America. Their preferred diet includes amphibians, fish, and crustaceans. When they are still young, they’ll primarily indulge in crabs, shrimp, and other invertebrates.

Reproduction and Lifespan

As popular as the electric eel might be, so much of their life is still a mystery. Scientists still don’t know much about the breeding process, though males and females work together for their brood. During a dry season, the female lays her eggs in the nest made by the male. These nests are made with the saliva of the male. Males fertilize the eggs, which can add up to 1,700 each year by the female.



Once the eggs are in the nest and fertilized, the eels die. The eggs slowly hatch, floating to the surface of the water after they become larvae. The water current brings them to New Zealand and other areas, though it can take them 17 months or more to reach their destination.



The average lifespan of an electric eel is anywhere from 12 to 22 years, though females generally live longer.

Electric Eel in fishing and cooking

Catching any type of eel is best done at sea because it means that they’ve reached their best size and fat content. Collecting electric eels can be difficult, but most anglers use equipment like baited long lines, spears, and baited traps commercially. Personal preference plays a role.



While most eels count as a delicacy that is worth the work, electric eels are much bonier. Their body featured little meat, but there are still many recipes online to show you how to sautee, bake, and cook the fish in other ways.

Population

This species tends to flourish throughout the regions they are found in, but researchers have found it difficult to determine their exact population. They are not legally allowed to be collected without a permit relating to scientific research, and locals cannot keep electric eels due to their risk to both populations of humans and fish if released.
