Yes they can Kill... The shock from an electric eel affects the body by altering physiological functions such as involuntary muscle actions and respiration. Symptoms of being shocked by an electric eel can be respiratory paralysis and cardiac failure. These symptoms may result in death. Eels also have powerful jaws and can bite a finger right off of a diver if they are not careful. This could in theory cause death if medical treatment was not made available soon. http://hypertextbook.com/facts/BarryLajnwand.shtml
Yes, a human adult could be killed by an Electric Eel shock. Probably by one defending itself, rather than while hunting. When they hunt they use lower voltage, just to stun their prey. but when frightened they can produce a lethal discharge. A juvenile doesn't produce such a lethal voltage, but an adult Electric Eel can produce anywhere from 500 to 650 volts when frightened, startled and defending itself. For more detail, please see the site listed below.
No water animals eats the electric eels since electric eels have very powerful shocks that can paralyze or hurt anything that gets its way. Humans have been known to eat electric eels on very rare occasions.
Humans do eat electric eels when they are dead. The electric eel's meat tastes like fish.
fish
They eat through their mouths.
other baby eels (dead ones)
to kill the fish that they eat
Electric eels feed on invertebrates, where adult eels eat fish and small mammals. First-born hatchlings will even eat other eggs and embryos from later batches. The juveniles will eat invertebrates such as shrimp or crab.
yes
yes but they only eat things smaller than their size
Electric eels are what is known as an "apex predator". These are predators that don't have any natural predators of their own. The electric eel has the ability to produce 600 volts of electricity through it's body which is an self-defense mechanism that makes it extremely difficult for anything to eat it. In fact, it has been noted that alligators have died from biting into an electric eel.
do not dirty the water
While it's theoretically possible for a shark to eat an electric eel, it's unlikely due to the eel's ability to produce high-voltage electric shocks as a defense mechanism. Sharks typically avoid electric eels to prevent injury or damage from the electric shocks.
