Special Abilities
Electricity (Ex) An electric eel can produce a powerful jolt of electricity from its tail, delivering the jolt with a successful touch attack. On a critical hit, the creature struck must make a DC 15 Fortitude save or be stunned for 1d4 rounds. The save DC is Constitution-based.

The electric eel is a curious fish that breathes air instead of water, yet certainly its most unusual characteristic is its ability to generate powerful jolts of electricity. An electric eel is 6 feet long and weighs 45 pounds.
