Electric eels are a fascinating species of fish that can produce powerful electric shocks. These shocks are used for stunning prey and protection, with some species capable of discharging up to 860 volts, the highest of any known animal. Interestingly, the question of whether electric eels produce alternating current (AC) or direct current (DC) has been a topic of discussion, with researchers speculating that they may even switch between the two. This unique ability has sparked curiosity among scientists and enthusiasts alike, leading to further exploration of the electrifying capabilities of these creatures.

Electric eels are not closely related to true eels
The electric eel's scientific name is Electrophorus electricus, and it was first described by Carl Linnaeus in 1766. They are native to South America and are found in freshwater habitats such as streams, swamps and pools. Electric eels have long, cylindrical bodies that can grow up to 6 feet 7 inches (2 meters) in length and weigh up to 44 pounds (20 kilograms). They have brown to black skin with a yellow or red underbelly, and their pectoral fins possess eight tiny radial bones at the tip.
One of the most notable features of electric eels is their ability to produce electricity. They have three electric organs containing cells called electrocytes, which create an electrical current of up to 600 volts when the eel senses prey or feels threatened. This current is a direct current (DC), which is a rare type of signal in the animal kingdom. In contrast, most electric fish produce alternating currents (AC), which create a "pop-pop-pop" sound when recorded underwater.
Electric eels are air-breathing fish, which means they need to surface every ten minutes to breathe. They have small eyes with poor vision but can hear well underwater. They are mostly nocturnal and use electrolocation to hunt, primarily feeding on fish such as armoured catfish. Electric eels can also work together to hunt, herding shoals of fish and then launching joint strikes.
In summary, electric eels are not closely related to true eels and exhibit a range of unique characteristics, including their electric abilities and air-breathing behaviour. They are an intriguing example of the diversity and adaptability found in the natural world, particularly among fish species.

Electric eels can produce both low and high-voltage shocks
Electric eels can produce both low- and high-voltage shocks. They are one of the only known fish to produce such a strong discharge, with a maximum discharge from the main organ of at least 600 volts, making them the most powerful of all electric fishes. The electric eel produces its strong discharge extremely rapidly, at a rate of up to 500 hertz, meaning each shock lasts only about two milliseconds.
Electric eels use three electric organs to produce two types of electric organ discharges: low voltage and high voltage. The low-voltage electricity is used for electrolocation, which helps the eel sense its environment and locate prey. The main organ and Hunter's organ produce the high-voltage shocks, which are used for stunning prey and deterring predators.
The high-voltage shocks are generated by stacking around 6,000 electrocytes in series in the eel's main organ, with 35 such stacks in parallel on each side of the body. The electrocytes are modified muscle cells, containing the proteins actin and desmin in a loose network formation. The electrocytes produce an electric current in a similar way to a battery, with stacked plates creating an electrical charge.
The electric eel's shocks are not necessarily dangerous to humans. Although the discharge is high voltage, it has low amperage (around 1 amp), so it is not lethal. However, it is still powerful enough to deter most other animals, except for the alligator-like caiman, which has been known to bite an electric eel in half and devour it.

Electric eels use electricity for stunning prey and self-defence
Electric eels are a genus of neotropical freshwater fish from South America. They are known for their ability to stun prey by generating electricity, delivering shocks of up to 860 volts. They are also able to use electricity for self-defence.
Electric eels have three pairs of electric organs, which make up about 80% of their bodies: the main organ, Hunter's organ, and Sachs' organ. These organs give electric eels the ability to generate two types of electric discharges: low voltage and high voltage. The main organ is used to stun prey or deter predators, while Sachs' organ is used for electrolocation, with a discharge of about 10 volts at a frequency of 25 Hz. The total electric current delivered during each pulse can reach about 1 ampere.
Electric eels can locate their prey using electroreceptors derived from the lateral line organ in their heads. They also have motion-sensitive hairs along their bodies that detect any slight pressure changes in the surrounding water. When the eel suspects that prey is nearby, it emits two rapid electric pulses, called a doublet, which causes the prey's muscles to twitch involuntarily. The eel then emits a series of high-voltage pulses (up to 400 per second) to paralyze and consume its prey.
Electric eels are mostly nocturnal and inhabit quiet, slow-moving waters in the Amazon and Orinoco Rivers. They are able to swim forward, backward, and hover as they search for prey. They are closely related to catfish and carp, rather than other eel families.

Electric eels can electrolocate and communicate using weak charges
Electric eels are not closely related to true eels (Anguilliformes) but are members of the electroreceptive knifefish order Gymnotiformes. They are nocturnal, obligate air-breathing animals with poor vision, and they rely on their electrolocation abilities to navigate. Electric eels can electrolocate and communicate using weak charges. They have three electric organs and produce two types of discharge: to electrolocate and to stun. The Sach’s organ and one half of the Hunter’s organ produce weak electric impulses, which the eels use to navigate, seek out prey, and signal one another for courtship during the breeding season.
Electric eels generate large electric currents through a highly specialized nervous system that synchronizes the activity of disc-shaped, electricity-producing cells packed into a specialized electric organ. Each electrogenic cell carries a negative charge on its outside compared to its inside. When a command signal arrives, a neurotransmitter chemical is released, creating a transient path with low electrical resistance that connects the inside and outside of one side of the cell. This behavior is similar to that of a battery, with the activated side carrying a negative charge and the opposite side carrying a positive one.
The electric eel's relative, the bluntnose knifefish, has evolved a similar form of electrolocation. It may have developed this ability to mimic the electric eel, possibly to convince predators that an electric eel is nearby and that they should keep their distance. This is known as Batesian mimicry.
Electric eels can deliver a powerful electric shock of at least 600 volts, making them the most powerful of all electric fishes. However, they are not particularly aggressive and will only attack if they feel cornered. It is very rare for people to be killed by electric eels.

Electric eels are capable of generating the highest voltage discharge of any known animal
The maximum discharge from the main organ is at least 600 volts, making electric eels the most powerful of all electric fishes. In 2019, a newly identified species of electric eel, Electrophorus voltai, was discovered to produce the highest voltage ever recorded in an animal. This species can discharge up to 860 volts, significantly more than the 650 volts generated by the previously known species, Electrophorus electricus.
The ability to produce such high-voltage, high-frequency pulses is due to the large quantity of electrocytes available in the electric eel's main organ. These electrocytes are stacked in series, with each stack containing thousands of electrocytes, and there are multiple stacks on each side of the body. The electric eel's high-voltage discharge is also a result of the low conductivity of the water in its environment. The small amount of dissolved salts in the water makes it less electrically conductive, so the eels need to produce stronger discharges to capture prey.
The discovery of this new species of electric eel with its extremely high voltage discharge has provided new insights into the diversity of electric eels and other electric fishes in South America. It has also inspired new ideas for improving technology and treating diseases, such as using artificial electrocytes as a power source for medical implants.
