1. Electric Eel
Considered one of the most dangerous fish in the World, the electric eel (Electrophorus electricus) is known for its high-voltage electric shock.
It can generate up to 600 volts of electricity and can be used to attack prey or defend itself from predators.
Despite its name, the electric eel is not an eel but rather a type of knife fish. Its shock can be fatal to humans and cause cardiac arrest or respiratory failure.
If you’re ever in the waters where electric eels inhabit, be extremely cautious and stay away from these electric killers.
