The electric eel is found in the rivers of South America, mostly the Amazon. It is actually a fish that does not have either a spine or teeth. It grows to about 2.5 m in length and its vital organs are located near its head. The rest of the body comprises muscles that generate electricity, and the nerve endings that discharge electricity. It uses small amounts of electricity to navigate through waters, to communicate and to stun small fish for feeding. However, it has the ability to discharge more than 600 volts of electricity, enough to create the sensation of shock on a human being.
