electric fish (redirected from Strongly electric fish)

electric fish, name for various fish that produce electricity by means of organs usually developed from modified muscle tissue. The electric eel (Electrophorus electricus), a South American freshwater fish related to the carp, has organs along the ventral surface capable of producing from 450 to 600 volts of electricity—enough to light a neon bulb. Other electric fish include the electric ray, or torpedo; a freshwater electric catfish with a jellylike subcutaneous electric organ (probably of epidermal origin) that extends over the whole body; and various species of stargazer. All these fish produce electricity at will to paralyze or kill their prey, to repel their enemies, and to aid in navigation. Recent experiments have shown that when an electric eel is in motion it generates pulses of low-energy electricity which serve to detect the presence of nearby objects. Scientists believe that electric organs in fishes may function also in communication between individuals. Electric eels are classified in the phylum Chordata, subphylum Vertebrata, class Osteichthyes, order Cypriniformes, family Electrophoridae.
