Electric eels have an elongated, grey or brown body and grow up to 2.5 meters long.
Approximately every 15 seconds, electric eels gasp for air in the water, absorbing oxygen through the mucous membrane of their mouth.
Thrilling: Electric eels have electric organs with which they can build up electric fields. The animals use weak signals to orient themselves or communicate with each other. However, the electric eel can also emit strong electric shocks of up to 860 volts, with which it kills prey or defends itself.
