Detailed explanation-1: -The electric organs of two strongly electric fish, the torpedo ray and the electric eel were first studied in the 1770s by John Walsh, Hugh Williamson, and John Hunter. Charles Darwin used them as an instance of convergent evolution in his 1859 On the Origin of Species.

Detailed explanation-2: -Strongly electric fish, namely the electric eels, the electric catfishes, the electric rays, and the stargazers, have an electric organ discharge powerful enough to stun prey or be used for defence, and navigation.

Detailed explanation-3: -Torpedo is an electric ray. It is a cartilaginous fish. These are capable of producing electric discharge ranging from 8 to 220 volts. They use electric discharge to stun prey and for defence.

Detailed explanation-4: -Electric eels can generate an electrical charge of up to 600 volts in order to stun prey and keep predators at bay.

Detailed explanation-5: -The electric eels are a genus, Electrophorus, of neotropical freshwater fish from South America in the family Gymnotidae. They are known for their ability to stun their prey by generating electricity, delivering shocks at up to 860 volts.
