生態学
; 新鮮な水 底生の; potamodromous (Ref. 51243). Tropical
Africa: Gambia, Senegal, Niger, Volta and Chad basins. Sahelo-Soudanian basins and the coastal basins of the rivers Cavally, Bandama, Sassandra, Comoé, Mono, Ouémé, Ogun and Culufi; Congo basin. Two subspecies exist: Mormyrus rume rume: West Africa and Chad System; Mormyrus rume proboscirostris: middle and upper Congo River.
初回成熟時の長さ / サイズ / 重さ / 年齢
成熟: Lm ?, range 33 - ? cm
Max length : 100.0 cm SL オス/雌雄の選別がない; (Ref. 31256); 最大公表体重: 5.3 kg (Ref. 2915); 最大記録サイズ: 6 年 (Ref. 2744)
背面の脊椎 (合計) : 0; 背鰭 (合計) : 72 - 95; 肛門の骨: 0; 臀鰭: 16 - 21. Anal fin base 4.6-6.5x that of dorsal fin; 20-26 scales on caudal peduncle; body height 3.5-6.1x SL; height of caudal peduncle 1.3-3.0x of its length.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Affinities: look-alike of M. subundulatus and M. tapirus. Feeds on insects and larvae (Ref.13851). Generates electric organ discharge (EOD) of long duration that seems to correlate with territorial behavior of the species (Ref. 10460; 10601).
