Etymology

From cat + fish. Likely so named for its prominent barbels like a cat's whiskers. Compare West Frisian katfisk (“catfish”), Dutch katvis (“catfish”). Compare also German Seekatze (“catfish”, literally “sea-cat”).

From the 2010 documentary Catfish, supposedly inspired by the practice of fishermen keeping cod active by storing them with catfish (see sense 1) which nip at their tails.
