توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 5 - 7; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 14; مهره ها: 50 - 56. Cylindrical body (Ref. 28149, Ref. 46409). Upper jaw a little longer than lower jaw (Ref. 28149). Number of dorsal finlets: 5-7 (Ref. 28149, Ref. 51884); used to distinguish Polypterus palmas polli from P. p. palmas and P. p. buettikoferi (Ref. 28149). Pectoral fin not reaching dorsal fin origin (Ref. 28149). Ganoid scales (Ref. 42904): 52-55 lateral line scales, 32-39 scales around body, 22-28 predorsal scales (Ref. 28149, Ref. 51884). Dorsal surface and flanks with large black blotches, forming a dense reticulate pattern, ventral surface uniform pale (Ref. 28149). The fleshy base of the pectoral fin with a large grey to black spot (Ref. 28149, Ref. 46409). Dorsal fin spotted, pectoral fin with a striped pattern in some specimens, pelvic fin pale and anal fin sometimes slightly colored (Ref. 28149).
Body shape (shape guide): elongated; Cross section: circular.
Facultative air-breathing (Ref. 126274); This entomophagous fish lives in swamps and zones of flood (Ref. 41580).
