Etymology: Enteromius: Greek, enteron = intestine + Greek, myo, mys = muscle (Ref. 45335).
More on author: Rüppell.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 23°C - 27°C (Ref. 12468)
Africa: Nile River, Volta basin (Ref. 2801, 2940), Lake Albert (Ref. 2801), Benué River (Ref. 2801, 2940, 81282), Chad and Niger basin (Ref. 2940, 81282). Reports from Lake Edward system (Ref. 2801, 4903, 47905) are misidentifications for Enteromius alberti or E. cf. mimus (Ref. 127947).

Morphology | Morphometrics
soft rays: 8. Diagnosis: last simple dorsal-fin ray smooth on hind margin; scale formula 4.5-5.5/27-32/4.5; 2.5 scales between lateral line and pelvic-fin base; 12-14 scales around caudal peduncle; 7-8 branched dorsal fin rays; two pairs of barbels; anterior barbell not reaching to anterior margin of eye/not extending beyond centre of eye; posterior barbel reaching to, or extending beyond, posterior half of eye; lateral line complete and deeply depressed below dorsal fin; 4-6 short and widely spaced gill rakers on lower limb of first gill arch; maximum reported size 89 mm SL; 3 small, independent, round spots on sides; 2nd spot located slightly behind vertical line from last simple dorsal-fin ray; average distance centres 2nd-3rd spot/distance centres 1st-2nd spot (= RDT) is over 1.4 (Ref. 2940, 81282).
Three forms exist: West African typical form, Lepidus form with supplementary spots between 3 typical spots and larvae form with numerous aligned points (Ref. 2940).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00546 - 0.02648), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
