Electric Eels Generate 600 Volts Of Electrical Energy

Eels look a bit like underwater snakes, but they are a kind of fish. Electric eels may be the most well-known kind, but you do not want to come across an electric eel. When threatened, these guys can emit a massive shock of electricity, equal to 600 volts.

That kind of shock could stun an adult human and even cause electrocution. Yet the eel is biologically hard-wired not to be adversely affected by the electricity coursing through the water – it has specialized cells that protect it from being electrocuted.
