Electric Eel and electrocution

The Electric Eel (Electrophorus electricus) is a freshwater fish in the Gymnotidae family of electric eels. It is not an eel. It is a Gymnotiforme in the knifefish family. It is related to the Catfish. 

The Electric Eel has three pairs of abdominal (stomach) organs that produce electricity: the main organ, the Hunter’s organ, and the Sach’s organ, which are made of electrocytes. Scientists think it has enough electricity, up to 500 volts, to produce a ‘stun gun’ shock, or electrocution, in humans and its prey.

Why doesn’t the Electric Eel electrocute itself?
