Africa: The subspecies Polypterus bichir bichir is known from the Chad basin, Nile River basin and Lake Turkana (Ref. 2835, 81263). Reports from Lake Turkana and the Ouémé are questionable as unsupported by photographs or museum specimens (Ref. 122071). The subspecies Polypterus bichir lapradei is known from the rivers Senegal, Gambia, Geba, Volta and Niger (Ref. 2835, 81263).

簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 13 - 18; 背鰭 (合計): 0; 肛門の骨 0; 臀鰭: 13 - 16; 脊つい: 61 - 62. Diagnosis: Polypterus bichir is characterized by a lower jaw slightly longer than upper jaw and a pectoral fin reaching the first dorsal ray (Ref. 2835, 42908, 81263). The subspecies P. bichir bichir has 63 to 70 scales in lateral line, 14 to 18 dorsal fin rays and 11 to 13 pelvic fin rays (Ref. 367, 81263). The subspecies P. bichir lapradei has 58 to 68 scales in lateral line, 13 to 15 dorsal fin rays and 13 to 16 pelvic fin rays (Ref. 367, 81263).

生物学     用語集 (例 epibenthic)

Facultative air-breathing (Ref. 126274); Polypterus bichir bichir likes shallow water and will often lie basking fo hours near the surface, but when swimming the fish is very pliant, and can turn and twist like an eel (Ref. 4904). The eggs are deposited in weeds, where the adult fish guards the eggs and young (Ref. 36900). It feeds on bottom-feeding fish (Ref. 36900) and is essentially piscivorous (Ref. 367).
