Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water.
Eponymy: Auguste Henri André Duméril (1812–1870), was a physician and zoologist like his father (see next entry) and followed much in his father’s footsteps. [...] (Ref. 128868), visit book page.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 65 - 81; شعاع نرم باله مخرجي: 51 - 62; مهره ها: 57 - 62. Diagnosis: head oval-shaped to rectangular dorsally; snout broadly rounded; eyes more laterally placed; frontal fontanelle extremely long and narrow; occipital fontanelle oval-shaped to rounded; tooth plates extremely broad (Ref. 248). Supraorbital and `dermosphenotic' bones separated; dermosphenotic somewhat reduced and shows a clearly marked notch (Ref. 248, 101841) although this notch is not observed in all specimens (Ref. 101841). Pectoral spine straight and robust; gill rakers relatively long and distantly set; openings of the secondary sensory canals regularly arranged (Ref. 248). Suprabranchial organ reduced to virtually absent (Ref. 248, 101841).
Colouration: preserved fish show uniform colouration: dorsum, flanks and upper side of paired fins dark brown; ventrum and ventral parts of paired fins light grey to beige; no information known on colouration of living specimens (Ref. 248).
Body shape (shape guide): elongated; Cross section: circular.
Facultative air-breathing (Ref. 126274)
