Catfish have no scaleIn most biological nomenclature, a scale ( Greek lepid is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopteran species, scales are plates on the surface of the insect wing, and provide coloration. Scales are quites. All catfish, except members of Malapteruridae (electric catfish), posses a strong, hollow, bonified leading ray on their dorsalDorsal Fin of the Orca A dorsal fin is a fin located on the backs of fishes, whales, dolphins and porpoises. Its main purpose is to stabilise the animal against rolling and assist in sudden turns. Some animals have developed dorsal fins with protective fu and pectoral fins, through which a stinging protein can be delivered if the fish is irritated. In members of the family Plotosidae, and of the genus Heteropneustes , this protein is so strong it may hospitalize humans unfortunate enough to receive a sting.
Catfish are important food fish throughout the world. Ictalurids are cultivated in North America (especially in the Deep South), while Clariids and Pangasiids are heavily cultured in Africa and Asia. There is also a large and growing ornamental fish trade, with catfish and plecos a popular component of many aquaria.
