A family of freshwater fish from South America characterized by their ability to generate and detect electrical fields for navigation and communication.
From 'Gymnotus' (type genus) plus '-idae' (family suffix in scientific naming). The family includes electric eels and various knife fish species.
Electric eels aren't eels at all—they're actually fish in a completely different family! They evolved electricity independently from electric catfish. Nature invented the same superpower twice!
