Electric eels are a type of electric knifefish that can grow up to 8 feet long and weigh 44 pounds. They are found in the murky backwaters of the Amazon and use their powerful electric shocks to detect and electrocute prey, as well as to defend themselves against predators. A single shock from an electric eel can incapacitate a human and potentially cause death by drowning or heart failure, especially if multiple shocks are involved. While documented cases of human deaths are rare, the powerful voltage produced by these creatures, which can reach up to 860 volts, poses a significant threat.

What You'll Learn
Electric eels can generate up to 860 volts of electricity
Electric eels are known to be deadly predators. They can produce a significant amount of electricity, with a full-grown electric eel generating about 600 volts of electricity in short, intense bursts lasting only about 2 milliseconds. This is achieved through thousands of muscle cells, each contributing a tiny current. The electric charge is used for navigation, hunting, and defence, with the eels emitting a low voltage for navigation and high-voltage bursts for hunting or defence.
In 2019, a new species of electric eel, Electrophorus voltai, was discovered, which can generate even higher voltages of up to 860 volts, significantly more than the previously recorded maximum of 650 volts. This makes it the strongest bioelectricity generator in nature, with a higher voltage than any other known animal. The discovery of this new species suggests that there may be many more species yet to be discovered in the biodiverse region of Amazonia.
The electric shock from an eel can be extremely harmful to humans, even when the eel is out of the water. The impact on a human depends on the voltage, current, hertz, pulse duration, and the number of contact points between the eel and the human. A shock from an electric eel can cause a brief, numbing jolt similar to that of a stun gun. While a single shock may not be fatal, it can incapacitate a person, causing loss of muscle control and painful muscle contractions.
Multiple shocks from an electric eel can lead to more severe consequences, including respiratory or heart failure, and even death. In addition, the shock can cause a person to fall into water and drown. However, the impact of an electric eel shock on a human also depends on the size of the eel and the condition of the person's skin. The high voltage and low amperage of the electric eel's shock mean that it may not be dangerous to humans, and there are few documented cases of deaths caused by electric eels. Nevertheless, it is essential to exercise caution when encountering these powerful creatures.

The shock can cause serious injury or death
Electric eels can produce a powerful shock of up to 860 volts, which is enough to cause serious injury or death in humans. The shock can lead to loss of muscle control and painful muscle contractions, which can cause a person to pass out. If this happens in water, the person can drown within 60 seconds.
The high voltage of the electric eel's shock can also cause electrical injuries and burns. The damage from a shock above 500 volts can be severe, and dielectric breakdown of the skin occurs at voltages above 450–600 volts. However, the occurrence of electrical burns depends on various factors, including the conditions of the skin.
In addition to the voltage, the harm caused by an electric eel shock can depend on the current, hertz, pulse duration, and the number of contact points between the eel and the human. The duration of the shock is also a factor, as a longer shock will deliver more electrical energy and cause greater harm.
While documented cases of human deaths from electric eels are rare, the shock can be fatal, especially if multiple shocks are involved. Multiple shocks can cause respiratory or heart failure, and there is a risk of drowning if the shock incapacitates a person in water.
To minimise the risk of serious injury or death from an electric eel shock, it is important to avoid direct contact with these creatures and not attempt to handle them with bare hands. Electric-shielding rubber gloves and boots can provide protection if handling is necessary.

The eel shocks itself but doesn't feel it
Electric eels can produce a powerful shock of up to 600 volts, which is enough to incapacitate or even kill a human. The electric shock can cause serious injury, heart failure, or respiratory failure, especially if multiple shocks are involved.
Interestingly, electric eels do sometimes shock themselves. However, they don't feel the shock because it is distributed over their entire body and is very brief. The electric current they generate is so short, lasting only about 2 milliseconds, that they don't perceive it. This is similar to how humans might experience a less intense shock if they prepare themselves and subconsciously make the duration of the shock shorter.
Electric eels have specialized musculature for the storage and discharge of electricity. Their bodies contain thousands of muscle cells, or electrocytes, that each create a tiny current. These electrocytes are arranged like stacks of batteries in three separate organs. The rapid transfer of sodium ions along these electrocytes generates an electrical current at either high or low voltage, depending on the organ producing the charge.
While the electric eel uses its electrical ability for navigation, hunting, and defense, it is careful to avoid shocking itself too frequently. The electric eel's conductive parts may also exclude vital organs, further reducing the risk of self-electrocution.

They can jump out of the water to shock threats
Electric eels are indeed capable of jumping out of the water to shock threats. This behaviour was first observed by 19th-century explorer Alexander von Humboldt, who witnessed electric eels leaping from the Amazon's waters to shock horses. However, for over 200 years, there were no similar scientific reports of eels performing this behaviour, and many were sceptical of von Humboldt's account.
In recent times, biologist Kenneth Catania has provided credence to von Humboldt's story. Through experiments, Catania observed electric eels leaping from the water to attack a conductive rod and plate, as well as a plastic alligator head covered with a conductive metal strip and LED lights. The eels were able to deliver shocks with greater power and over a larger area when out of the water, making this behaviour an effective defence mechanism against terrestrial and semiaquatic predators.
The ability to jump out of the water and deliver a shock is particularly useful for eels during the dry season in the Amazon, when water levels are low and they are more vulnerable to predators. By leaping out of the water, eels can also better protect themselves from threats that are partially submerged in the water. This behaviour may also be a result of the eel's natural instinct to press its chin against a threat to deliver a shock, as observed by Catania during his experiments.
The electric shock produced by an eel out of the water can be as high as 600 volts, five times the power of a standard U.S. wall socket. This high-voltage shock can cause serious injury or even death in humans, especially if multiple shocks are involved. The extent of harm caused by an electric eel out of the water will depend on factors such as voltage, current, hertz, pulse duration, and the number of contact points between the eel and the recipient of the shock.

Electric eels are not actually eels
A full-grown electric eel can generate about 600 volts of electricity, enough to incapacitate or even kill a human, especially if multiple shocks are involved. They can also cause painful muscle contractions and loss of muscle control. However, despite their name, electric eels are not actually closely related to true eels (Anguilliformes). Instead, they are members of the knifefish order Gymnotiformes, which also includes the banded knifefish and is more closely related to carp and catfish.
Electric eels are found in the streams, rivers, and ponds of South America, particularly in the Amazon, and can grow up to 8 feet (2.5 meters) in length and weigh up to 44 pounds (20 kilograms). They are nocturnal, air-breathing animals with poor vision, and they use electricity to navigate, hunt, and defend themselves. They emit a constant electric charge of about 10 volts, which helps them find their way in muddy waters and identify prey.
The electric eel, or Electrophorus electricus, was first described by Carl Linnaeus in 1766 based on early field research in South America. In 1864, Theodore Gill moved the species to its own genus, Electrophorus, derived from the Greek words for "amber, a substance able to hold static electricity" and "I carry," thus meaning "electricity bearer." More recently, in 2019, C. David de Santana and colleagues divided the species into three distinct species based on DNA divergence, ecology, anatomy, and electrical ability.
While they are indeed dangerous, electric eels are not aggressive and will only attack if they feel threatened. They have been known to jump out of the water to shock prey or threats in the air, and they can deliver intermittent electric shocks for at least an hour without tiring. However, they are not invincible; after giving multiple shocks, they need to rest and replenish their energy.
