Clarias or Clarius Angolan is a large predatory catfish, belonging to the Clarias family. Outwardly, it resembles a herringbone catfish, but in fact there are many differences between them. For example, in the clarias, the dorsal fin extends along the entire length, while in the `sac, ` it is short. Both these catfish can breathe atmospheric air, but if the first of them breathes with the help of a suprabranch organ, then the second for breathing uses special bags located on both sides of the back. The similarity of both soms is that on the first rays of the pectoral fins there are thorns, the of which are very painful.
