This is because the electric eel body is a very thick layer of special fat, the electric eel body of this layer of fat is an insulator, and this fat is also the electric eel's protective layer, to protect the electric eel in their own discharge, their own unaffected, but also to protect their own not to be companion of the electricity to the electricity. The world is full of weapons. There are always many very special creatures in nature.
The electric eel is a creature that uses electricity to stun its prey. The electric eel is a kind of fish, is a powerful discharge ability, can say if in the water, the electric eel call us people, we will be electric eel to stun, and even will be electrocuted to death is also possible. And water is conductive, we can see the electric eel's discharge ability is very powerful. This layer of fat on the body of the electric eel is an insulator, as the protective layer of the electric eel, it not only protects the electric eel from being accidentally electrocuted by its own electricity, but also protects itself from being electrocuted by its own kind. If the electric eel will be affected by their own electricity, then the electric eel species would have long been extinct, because when they can not find food to eat, they can kill their own kind, will be affected by their own electricity, then certainly will be affected by the companion's electricity. But this is all unnatural, after all, the same kind of poisonous snakes will not attack each other themselves.
The electric eel has a strong discharge ability, but not that come up, the electric eel will release all of its electricity, it has a strong control of its own discharge ability, at the same time, the electric eel how much discharge to represent the different meanings of the electric eel. If the electric eel releases very low power, then this represents a warning, test. And when it releases high power, it's a sign that it's taking you for granted and wants to take you down in one fell swoop and kill you as its food.
Because the electric eel lives in water, and we know that water is an insulator and conducts electricity, so the electric eel is very dominant in the water, because the water will have the electric eel to release the electricity increased, so that it will be easier to kill the prey.
