Did you know?

For centuries, a catfish was merely a type of fish with a distinctive face. Then, in 2010, Ariel Schulman released Catfish, a documentary about his brother Nev's experiences with a woman who pretended to be someone else online. (The movie was popular enough to spawn a television show by the same title.) In the documentary, the woman's husband explained the title with an anecdote about how fishermen transporting live cod used to put catfish in with the cod on long-haul shipments to keep the desirable cod active and alert until arrival. The man implied that his wife was like those catfish, keeping the lives of others fresh and interesting.

Word History

Etymology

Noun

cat entry 1 + fish entry 1; so called from the whiskerlike appearance of the barbels surrounding the fish's mouth; (sense 2) after Catfish (2010), a documentary film about a man who through social networking develops remote relationships with members of a family whose life histories have been fabricated to various degrees

Note: The title of the film, directed by Henry Joost and Ariel Schulman, is based on a story told by the husband of the woman responsible for the fabrications. He explains that at one time cod were shipped live in tanks from Alaska to China. The inactive cod would become mushy and tasteless, until someone came upon the idea of placing catfish in the tanks to stimulate them. To the man, his wife has played a role similar to that of the catfish in the tank: "… there are those people who are catfish in life. And they keep you on your toes. They keep you guessing, they keep you thinking, they keep you fresh." As subsequent investigation has uncovered, the catfish tale is much older than the film. It was used for different comparative purposes by the British journalist Henry Nevinson in an essay "The Catfish" published as part of a collection in 1913 (Essays in Rebellion, London, James Nisbet & Co.). The tale itself appears to be a fabrication, as cod were not shipped across oceans in tanks, and catfish, being bottom-feeders, are not predators of cod.
