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).
More on author: Bloch.

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).

Краткое описание определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 9; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 12; позвонки: 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).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00412 - 0.00732), b=3.13 (3.05 - 3.21), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 4.1 ±0.71 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (K=0.27-0.59; tmax=5; Fec < 10,000).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
