ELI5: how does eels produce electricity? And why does it not kill the eels or other fish in the water?

They actually sometime die by accident by their own shock. But only when the electric current passes through its vital organs.

In most cases they avoid this though. Electricity follows the path of least resistance and this they use to dodge the current by flexing their body in a certain way. They make sure their denser parts or the body are in the line of fire of their heart, thus protecting it from the current.

They do hunt in packs in some place, was found out a few years ago. They communicate with low currents and possess hairs that recognize water pressure differences around them. They synchronize their attack... An impressive feat indeed!
