The positive and negative charges in electric eels are usually balanced. Once the enemy is found, the brain center immediately sends a signal to the cells through the spinal nerve. When the battery receives the signal, it will generate a voltage of about 0. 15 volts.
This kind of cell is distributed on all sides of the body of electric eel. These batteries are like small stacked batteries. When one of them receives the signal, thousands of cells will generate electricity at the same time. If the tail is negative and the head is positive, the current will flow from the fish tail to the fish head. The generated electric field is two or three meters in diameter, which is enough to corona any animal.
Brief introduction of electric eel
The electric eel originated from the ocean, then moved to Danshui River and grew up, and it has its territory in the Atlantic Ocean, the Pacific Ocean and the Indian Ocean. The main river where they migrate is the Amazon River in South America. Adult electric eels can reach 2 meters in length and weigh 20 kilograms, which is different from all kinds of eels that people often eat. In fact, electric eels are not eels, but are closer to catfish in biological classification.
The electric eel can output 800 volts at the highest moment, which can corona a cow. Crocodiles are afraid of it. I have seen many news that crocodiles were electrocuted by electric eels. In fact, there are many kinds of fish that can generate electricity in nature, but the electric eel is the one with the largest power generation, so it is also listed as one of the most dangerous freshwater fish in the world.
