Thorny catfish

Thorny catfish, Raphaels, or Talking catfish are a family, Doradidae, of catfishes native to South America, primarily in Brazil, Peru, and the Guianas. There are approximately 35 genera and 90 species.

Typical features of the family are a row of armored plates laterally along the body (known as scutes) often with spike like extensions along the center of the plates, three pairs of barbels (no nasal barbels), and 4″“6 rays on the dorsal fin with a spine on the anterior (first) ray. The adipose fin is usually present. These fish are sometimes called “Talking catfish” because of their ability to produce sound by moving their pectoral spine or vibrating their swim bladder.
