Etymology: Hepsetus: Greek, epsetas, -e, -on = boiled, but there is the following sentence: "oí epsetoi" = certain fishes, and also could be related to "psetta" = grouper (Ref. 45335); odoe: The specific name is possibly derived from the Greek 'odon' which means tooth (Brown 1954) (Ref. 88135).

; 淡水 居於水底的; pH range: 6.0 - 7.5; dH range: ? - 18; 河川洄游 (Ref. 51243). 熱帶; 26°C - 28°C (Ref. 2060)
Africa: easternmost part of West Africa, from the Sassandra River, Ivory Coast, in the west to the Shari River, Central African Republic, in the east; and southwards up to the Kribi River in Cameroon (Ref. 88135). Reports from outside this area refer to other species of Hepsetus (Ref. 88135, 93279, 93907, 108775).
非洲: 塞內加爾到安哥拉包括尼日，查德的佛塔河，奧克維河，剛果與尚比西河上游河廣泛分佈從; 以及在庫內內河，奧塔萬戈河與 Kafue 系統。 廣泛分佈於中央的與非洲西方部。 不存在於尼羅河; 尚比亞剛果與五大湖.(參考文獻 7248)

背棘 (總數) : 0; 背的軟條 (總數) : 9; 臀棘: 0; 臀鰭軟條: 12; 脊椎骨: 45 - 49. Diagnosis: This species is distinguished from all other Hepsetus species by the following unique combination of characters: number of lateral line scales low, 43–51; nostril-lower jaw distance short, 36.6–42.1% of head length; number of gill rakers high, 17–23; number of scales between dorsal fin and lateral line 7.5-9.5; number of scales between adipose fin and lateral line 4.5-6.5; head width broad, 32.8–42.3% of head length; and internasal distance high, 21.9–28.3% of head length (Ref. 88135).
附屬的外翼骨。 在 supraoperculum 上的知覺管。 鼻骨接近彼此。 在下頜上的三角形的關於皮膚的摺層與小的而且圓的上面之上。 體高 4.5-5.8 x SL。 頭部 3-3.7 x SL。 眼直徑 6-8個 x 頭長。 骨骼的公式 8-10/51-58/7-9,4. 區域眼睛上方紅色-橘色的標誌。 在眼後面的放射淡色與深色的條紋。 黑色的脂鰭。 粉紅色到淺灰色的鰭。 成魚在偶鰭上可能有黑色的斑點。
This species seems to prefer upper river courses or small rivers where Hydrocynus species are absent or scarce (Ref. 81278).
出現於大多數的沿海河川，湖與沼澤。 (參考文獻 3569) 偏愛安靜，深水域, 像大洪泛區的峽道與潟湖。 稚魚與魚苗居住於植物生長良好的邊緣棲息地。 成魚吃魚, 稚魚吃小型無脊椎動物與魚。 多次產卵的魚; 在夏天數個月以來繁殖。 相當生命期短又唯一的 4-5 年.(參考文獻 7248) 也用拖網捕獲。
