Did you know there are over 500 kinds of fish that produce electricity?
Let's check some of them out:
Electric eels work like a battery and can discharge from 350 to 650 volts of electricity. The head acts as the positive pole, and the tail is the negative pole of the battery. When it is moving, it can emit electric impulses up to 25 times per second. A 20-foot eel can produce enough electrical current to light 12 household light bulbs. Electric eels are mainly found in the Amazon. These guys can be dangerous and would not make a good pet.
The electric ray is known for being capable of producing an electric discharge, ranging from 8 to 220 volts depending on the species. They use this electric discharge to stun their prey, and to defend themselves from other predators.
Some bony fish and sharks have special pores on their heads that allow them to detect electrical currents. This extra sense helps them navigate or find prey in dark or muddy water.
