What does dorad mean?
A dorad is any of numerous South American freshwater fishes belonging to the family Doradidae, commonly known as thorny or talking catfishes. These fish are distinguished by their unusual body armor: rows of bony plates cover the skin, and many species bear sharp, serrated spines on the pectoral and dorsal fins. A remarkable trait shared by most dorads is their ability to make sounds — by moving their spines or their swim bladder they can produce audible croaks and clicks, which has led to the popular name 'talking catfish.' Native to rivers such as the Amazon and Orinoco basins, dorads are typically bottom-dwelling scavengers that feed on invertebrates and organic debris. The word appears chiefly in scientific writing about ichthyology and in the aquarium trade, where smaller dorad species are kept as ornamental fish. Though obscure outside specialist circles, it is a precise term for a distinctive and well-defined family of catfishes.

Etymology of dorad
The word 'dorad' comes from the genus name Doras, coined in nineteenth-century scientific nomenclature for a type species within the family Doradidae; the ultimate source is generally traced to an indigenous South American language. The suffix -id was added to form the family name Doradidae, and 'dorad' arose as a common noun referring to any member of that family. Its use remains largely confined to zoological literature and the aquarium hobby rather than general English vocabulary.
How dorad is actually used
