Electric eels are found in the freshwaters of the Amazon and Orinoco rivers of northern South America. They are obligate air-breathing animals with poor vision, and they primarily eat fish. Electric eels can grow to over 2 metres in length and weigh up to 20 kilograms. They produce electricity in electrocytes, which are special cells arranged like stacks of batteries and found in three separate organs. The rapid transfer of sodium ions along these electrocytes generates an electric current. This current can be discharged into the surrounding water, creating an electric shock.
| Characteristics | Values |
|---|---|
| How electricity is generated | Electric eels have special cells called electrocytes that are located in their electric organ. These electrocytes are arranged like stacks of batteries and produce electricity through a chemical reaction. |
| Voltage | Electric eels can produce a shock of up to 600 volts, which is enough to kill a human. |
| Current | The current generated by an electric eel can be as high as one ampere in air, but in water, it produces a larger voltage with a diminished current. |
| Shock delivery | Electric eels can control when they deliver a shock and are not affected by their own shocks due to their larger size, layers of insulating fat, and the distance of the electric organ from the brain. |
| Electrolocation | Electric eels use their electricity for electrolocation, which helps them navigate and locate prey in murky waters or at night. |
| Habitat | Electric eels are found in the freshwater habitats of the Amazon and Orinoco rivers in northern South America, seeking out slow-moving and oxygen-depleted waters. |
| Behavior | Electric eels are mostly nocturnal, have poor eyesight, and breathe air by surfacing every 10 minutes, allowing them to survive in low-oxygen environments. |
| Diet | They primarily feed on fish and small prey, using their electricity to stun their prey before consuming them whole. |
| Reproduction | Electric eels typically reproduce during the dry season or at the beginning of the wet season. Males create bubble nests for females to release their eggs for fertilization. |

Electric eels have three organs that help them create electricity
Electric eels are a genus of neotropical freshwater fish from South America. They are known for their ability to stun prey and defend themselves by generating electricity. In fact, they can deliver shocks of up to 860 volts!
Each of these organs produces electricity in a slightly different way. The main organ is the largest and most powerful, containing stacks of around 6,000 electrocytes (specialized muscle cells with both a positive and negative side) that can generate a maximum discharge of at least 600 volts. The Hunter's organ produces a middle voltage of around 38.5 to 56.5 volts, and the Sachs' organ produces a low voltage of nearly 10 volts.
Together, these organs allow the electric eel to produce two main types of electrical discharges: a high-voltage discharge to stun prey or deter predators, and a low-voltage discharge for electrolocation, or the ability to sense and navigate its environment. This makes electric eels very effective hunters, even in the dark and murky waters they inhabit.

Electric eels have poor eyesight and use electrolocation to navigate
Electric eels have poor eyesight and rely on their electrolocation abilities to navigate the murky backwaters of the Amazon and Orinoco rivers. They inhabit slow-moving, murky waters such as pools, swamps, and oxbow lakes, and their poor vision is complemented by their ability to use electric signals to navigate.
Electric eels emit a weak electric signal, which they use like a radar to navigate, find a mate, and locate prey. This is known as active electrolocation, where the fish emits electricity in murky water or at night to navigate. Electric eels have three special organs that help them create electricity: the main organ, the Hunter's organ, and the Sach's organ. These organs take up about 80% of the eel's body and allow them to produce electric impulses of different strengths, which serve different functions.
The electric eel's body contains stacks of modified muscle cells called electrocytes, which have both a positive and negative side. When triggered, these electrocytes discharge an electrical impulse into the surrounding water. The nervous system synchronizes the activity of these electrocytes, ensuring that thousands of cells activate at once to create a powerful electric current.
The electric eel's relative, the bluntnose knifefish, has evolved a similar form of electrolocation. This ability may serve as a form of Batesian mimicry, where the knifefish puts out a similar electrical signal to deter predators by convincing them that an electric eel is nearby.

Electric eels can leap out of water to deliver multiple electric shocks
Electric eels are a genus of neotropical freshwater fish from South America, known for their ability to stun prey and deter predators by generating electricity. They can grow to more than 2.5 meters in length and weigh up to 22 kilograms. They have poor eyesight and rely on their electrolocation abilities to navigate the murky waters of the Amazon and Orinoco rivers.
Electric eels have three special organs that help them create electricity: the main organ, the Hunter's organ, and the Sach's organ. These organs contain thousands of disc-shaped, electricity-producing cells called electrocytes, which are stacked like batteries. When triggered, these cells discharge an electric impulse, creating a powerful electric current.
In recent studies, it has been observed that electric eels can leap out of the water to deliver multiple electric shocks. They do this by leaping and pressing their chins, the most positively charged part of their bodies, against a predator or threat. With their negative pole still in the water, they create a closed electrical circuit, preventing the charge from dispersing into the water and instead dumping it into the target. This results in a highly powerful jolt that can drive away even large animals like horses.
While electric eels are not typically aggressive, they will attack if they feel cornered. They use weaker electric impulses for navigation, hunting, and communication, but can deliver powerful shocks when threatened. This ability to manipulate their electrical output showcases the sophistication and nuance of these fascinating creatures.

Electric eels can produce a shock of 600 volts, enough to kill a human
Electric eels are a genus of neotropical freshwater fish from South America. They are known for their ability to stun their prey by generating electricity, delivering shocks of up to 860 volts. However, on average, they can produce a shock of 600 volts, which is enough to kill a human.
Electric eels produce electricity in electrocytes, which are special cells arranged like stacks of batteries. These electrocytes are located in the eel's electric organ, which consists of three separate organs: the main organ, the Hunter's organ, and the Sachs's organ. The rapid transfer of sodium ions along the length of these electrocytes generates an electrical current at either high or low voltage, depending on the organ producing the charge.
The electric eel's nervous system plays a crucial role in generating electricity. It has a highly specialized nervous system that synchronizes the activity of disc-shaped, electricity-producing cells packed into its electric organ. When the brain sends a nerve signal to the electric organ, nerve cells release the neurotransmitter acetylcholine to trigger an electric organ discharge.
The electric eel's ability to produce such powerful shocks may also be due to its size. They can grow to more than two meters in length, making them much bigger than the fish and crustaceans they hunt. This larger size may contribute to the strength of their electric discharge. Additionally, the electric organ's location at the end of the body, far from the brain, may provide some protection from the shocks.
While a 600-volt shock from an electric eel can be deadly to humans, it is important to note that electric eels are not aggressive and rarely attack unless they feel cornered. Their electricity is also used for navigation and communication with other electric eels, showcasing the versatility of this unique ability.

Electric eels are found in the freshwaters of the Amazon and Orinoco rivers
Electric eels, or Electrophorus, are a genus of neotropical freshwater fish from northern South America. They are found in the Amazon and Orinoco rivers, seeking out slow-moving, murky waters such as pools, swamps, and oxbow lakes. They can also be found in streams and rocky environments.
These eels have very poor eyesight and rely on their electrolocation abilities to navigate their muddy habitats. They are able to generate electricity through a highly specialized nervous system that synchronizes the activity of disc-shaped, electricity-producing cells called electrocytes. These electrocytes are stacked like batteries in three specialized electric organs: the main organ, the Hunter's organ, and the Sach's organ.
When the electrocytes are triggered, they release a powerful electric current into the surrounding water. This current can be used to stun prey or protect against predators. While electric eels can deliver shocks of up to 860 volts, it is rare for them to be aggressive and they only attack when they feel cornered.
The study of electric eels has provided valuable insights into electricity and battery invention. In 1800, Italian scientist Alessandro Volta studied the electric eel, leading to the invention of the first battery. More recently, in 2008, researchers designed artificial electrocytes that could potentially be used as power sources for medical implants.
