how does electric eel doesn’t hurt themselves or damage a vital organ when they electrify their prey?

In: Biology

They flex themselves in a way so the electricity doesn’t flow through their hearts, when they open the ion channels letting sodium flow therefore reversing polarity and causing a difference in electric potential. When they are charging they make an “U” shape and when discharging it they stiffen up straight a ruler and the current flows parelel to their hearts.
