How do fish generate electricity? In the 18th century an explorer named Alexander Volt Humble saw a swarm of electric eels attacking horses with electric shocks while they were drinking water.
The veracity of Humboldt’s story has not yet been verified. As a result, the story is incredible and fabricated to most people. But the electrical capacity of fish is very common, and the electric eel is one of them. Deep in the water where light is scarce – electricity plays a major role in communication and catching prey.
About 350 species of fish in the world are able to generate electricity in their bodies and detect electrical signals. These fish are divided into two classes depending on the variation of electrical energy. Weak electric fish and strong electric fish respectively. Weak electric fish can only generate electricity up to 1 volt. Among the most powerful electric fish, the electric eel has the capacity to generate electric voltages up to 860 volts.
But how do fish produce electricity? Electric fish have thousands of disk-shaped electrical cells in their bodies known as electrocytes. Signals are transmitted to the mediums of the nervous system of the fish brain. India maintains a positive charge on the outside and a negative charge on the inside through the emission of electric potassium and sodium ions.
Positively charged potassium and sodium iron are absorbed at the electro site after the signal reaches the electro site through the nervous system. When a positive charge on one end of the electro site and a negative charge on the other end are added, the opposite religious charges on both sides generate electric current.
In other words, the electro site acts as a biological battery in this case. The signal from the brain arrives at the same time at each electro site. As a result, the electro sites act like hundreds of batteries connected in series and create powerful electric fields. There is actually a difference in the electrical field near any other fish. Electric fish can detect the location of prey by sensing differences with the help of electroreceptors on the body.
It is also possible to distinguish between living objects and inanimate objects by the size of the prey. Electric eels store most of the body’s electricity to injure prey through electric shocks. In addition to the electric eel, there are two other powerful power-generating fish. An electric catfish can generate up to 350 volts of electricity.
The other is an electric ray with a kidney-shaped electrical organ located behind the head. Which can generate up to 220 volts of electricity. The electrical power of electric fish may seem terrifying, but human casualties are very rare. However, more than one hobby can stop breathing or heart function. As a result, it is better to stay away from strong electric fish.
