Hepsetidae (African pikes)
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).

; agua dulce demersal; pH range: 6.0 - 7.5; dH range: ? - 18; potamodromo (Ref. 51243). Tropical; 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).

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 9; Espinas anales: 0; Radios blandos anales: 12; Vértebra: 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).
This species seems to prefer upper river courses or small rivers where Hydrocynus species are absent or scarce (Ref. 81278).
