How do electric eels adapt to the water?

Answer 1

Clearly they do have to mitigate the electrical impulse they receive, or they would kill themselves with their stronger defensive pulses. Unfortunately, it seems no one is really sure how they do this. One idea is that the position of the electric organs (on the flanks) helps prevent the pulse from traveling through the body, but data is sparse.

The electric eel (Electrophorus electricus), is an electric fish, and the only species of the genus Electrophorus. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is an apex predator in its South American range. Despite its name it is not an eel but rather a knifefish.The electric eel generates its characteristic electrical pulse in a manner similar to a battery, in which stacked plates produce an electrical charge. In the electric eel, some 5,000 to 6,000 stacked electroplaques are capable of producing a shock at up to 500 volts and 1 ampere of current (500 watts). Such a shock could be deadly for an adult human.
