Electric eel

Rows of electroplates lining its body enable the electric eel to immobilize or kill its prey, but it also uses electric charge to defend itself, to communicate and to navigate. Electric eels can grow to be almost 8 feet long, and the longer the eel's body is, the more electric charge it can put out.
