Heterobranchus is a genus of airbreathing catfishes native to Africa. However, H. palaeindicus, the only known extinct species of the genus, was discovered in the Siwalik Hills, India, dating to the Lower Pliocene.[1]

Depending on the exact species involved, fish of this genus reach from 64 to 150 cm (25 to 59 in) with H. longifilis being the largest strict freshwater fish in southern Africa, reaching 150 cm (59 in) SL and weighing up to 55 kg (121 lb).[2]
