What animals uses electricity to protect themself?

電鰻（electric eel）並非鰻魚，而與鯰魚（catfish）較為相近。
The electric eel, Electrophorus electricus, is a species of fish. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is an apex predator in its South American range. Despite its name it is not an eel at all but rather a knifefish.
