The numbfishes are a group of electric rays (order Torpediniformes) in the family Narcinidae. They are bottom-dwelling cartilaginous fishes with large, rounded pectoral fin discs and long tails. They can produce an electric discharge for defense, from which their scientific name is derived (Greek narke, meaning "paralysis").
