An electric eel can't breathe in water like fish do. It needs to come up to the surface and breathe the air above. Besides, they jump out of the water to attack any creature — this is their way of protecting themselves.

The eels' electric power can reach more than 600 volts. This burst of energy is enough to knock an adult horse off its feet. Previously, when people discovered this fish for the first time, they placed it in an aquarium and transported it around the world. In Europe, the eel was shown at exhibitions, and people considered it a real monster. But thanks to science, we now know how this fish generates electricity.
