An adult can stun its prey by firing 500 V discharges into the water as it hunts. Electric eels live in slow-moving freshwater creeks and swamps in the north-east of South America, including the Amazon and Orinoco basins. While they resemble eels in appearance, they’re actually a type of fish, known as a knifefish.

Do eels hunt with electricity?
When darkness comes, electric eels emerge from South American river bottoms to attack their prey with up to 860 volts of electricity—enough to kill a person. Now, scientists have revealed the snakelike fish don’t always go it alone: They hunt in packs, similar to wolves, orcas, and some species of tuna.
Are eels blind?
Eels have limited vision, they have rows of sensors on their head known as lateral lines. These help them detect movement in the water. Eels can travel over land, slithering through wet grass to get to a pond, river or lake.

Do eels actually shock you?
When the electric eel senses prey or feels threatened by a predator, electrocytes create an electrical current that can release up to 600 volts (if you are unlucky enough to be shocked by 600 volts, it won’t kill you on its own, but it will hurt).
Do eels have gender?
When identifying whether eels are males or females, the key feature to look for is whether the gonad has a distinct lobed or scalloped appearance, a little like a row of beads – if it does, the eel is male.
