This may come as a shock… but the electric eel (Electrophorus electricus) isn’t an eel. It's technically a knifefish and is more closely related to catfish and carp! This hefty critter, which can reach lengths of 8 ft (2.4 m) and weigh as much as 45 lbs (20.4 kg), delivers a charge of more than 650 volts. Its slimy skin acts like a shield, protecting it from its own shocks.
