The electric eel is an aquatic organism. They can discharge electricity in the water. The discharge is an effective means for them to protect themselves and hunt for food. Electric eels can release relatively strong electricity, even up to 800V, so many people call them "high-voltage lines in the water".
Electric eels have a relatively strong ability to discharge electricity, which is closely related to their body structure. The body and organ structure of electric eels is very different from that of fish living in the water. Their important organs, such as heart and liver, are very close to their heads. It can be said that their important organs are almost in the front of their bodies. In the rest of their bodies, there are many muscles and electric cells. These electrical cells are used to discharge electricity, and they are distributed in about 80% of their bodies. These cells are very much like batteries. If the electric eel wants to discharge, it will first transmit a signal through the nervous system, when stimulated by this signal, the electric cell will quickly let ions through the cell membrane, thus discharging.
As mentioned above, the electric eel's discharge ability is relatively strong. They can discharge electricity in the water, corona very large organisms, and even electrocute directly, such as crocodiles. Whether electric eels can electrocute humans is uncertain. Some large eels can electrocute humans, but some small eels cannot, because they emit relatively weak electricity. However, it is also possible for humans to drown after being electrocuted.
It should be noted that the eel is very powerful only when it is discharged in water, not in air. When they discharge electricity in the air, because their own resistance is smaller than that in the air, the current will pass directly through their bodies, and the electric eel may directly electrify itself.
