EVER HEARD OF ELECTROPHORUS ELECTRICUS?

I came across this amazing creature on TV.It might as well be used as a torturing tool for hardened criminals LOL! THE ELECTRIC EEL! Ever heard of it?

The electric eel (Electrophorus electricus) is an electric fish, and the only species in its genus.Despite their serpentine appearance, electric eels are not actually eels. Their scientific classification is closer to carp and catfish. These famous freshwater predators get their name from the enormous electrical charge they can generate to stun prey and dissuade predators. Their bodies contain electric organs with about 6,000 specialized cells called electrocytes that store power like tiny batteries. When threatened or attacking prey, these cells will discharge simultaneously, emitting a burst of at least 600 volts, five times the power of a standard U.S. wall socket!!!
HOW DO ELECTRIC EELS GENERATE VOLTAGE?
The source of their power is a battery-like array of cells known as electrocytes, which make up around 80 per cent of the eel's metre-long body. Disc-like in shape, these cells each acquire a small potential difference of around 1/10th of a volt by controlling the flow of sodium and potassium ions (charged atoms) across the cell membranes. Linked together in arrays of thousands of individual cells, the result is a kind of natural car battery, which releases its charge when the eel spots predators or prey. Up to 0.5kW of electric power is released per shock - enough to inflict significant injury on a human.

They live in the murky streams and ponds of the Amazon and Orinoco basins of South America, feeding mainly on fish, but also amphibians and even birds and small mammals. As air-breathers, they must come to the surface frequently. They also have poor eyesight, but can emit a low-level charge, less than 10 volts, which they use like radar to navigate and locate prey.
Electric eels can reach huge proportions, exceeding 8 feet (2.5 meters) in length and 44 pounds (20 kilograms) in weight. They have long, cylindrical bodies and flattened heads and are generally dark green or grayish on top with yellowish coloring underneath.
Human deaths from electric eels are extremely rare. However, multiple shocks can cause respiratory or heart failure!!! People have been known to drown in shallow water after a stunning jolt.
The shock of an electric eel has been known to knock a mighty horse off its feet!!!! Wow such a little devil!!
