The Doradidae are a family of catfishes also known as thorny catfishes, raphael catfishes or talking catfishes. These fish are native to South America, primarily the Amazon basin and the Guianas.

Doradids are omnivorous.[5]

Taxonomy

sister taxon to all other doradids.[6] This family is monophyletic and contains the subfamilies Doradinae, Astrodoradinae and Wertheimerinae.[3]

The Astrodoradinae contain the genera

Merodoras, Physopyxis, and Scorpiodoras
.

Distribution

Doradids occur in most

Pardo rivers and Kalyptodoras bahiensis from the Paraguaçu River.[6]

Appearance and anatomy

Doradids are easily recognized by a well-developed

anterior (first) ray.[7] These fish are sometimes called "talking catfish" because of their ability to produce sound by moving their pectoral spine or vibrating their swim bladder.[7] Sizes range from 3.5 cm (1.4 in) SL in Physopyxis lyra to 120 cm (47 in) FL and 20 kg (44 lb) in Oxydoras niger.[6]
