I want to know the answer to the following question:
The electric eel uses electric shock for defense and what other purpose?
All the background I'm provided with is that "The electric eel uses the same electric current to kill prey and to defend itself against animals (anacondas, caimans, egrets, jaguars, mountain lions, giant otters, humans, dogs, and cats) that ordinarily prey upon fish similar to an electric eel in size; the electric eel thus remains an apex predator in a predator-rich environment.". Is that enough to answer the question?
