Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 22°C - 25°C (Ref. 12468)
Africa: Lake Tana and Baro River (Ref. 31508, 58460). Specimens reported from Gojeb River, tributary of the Omo River (Ref. 31508, 58460), have been reidentified as Afronemacheilus kaffa (Ref. 94278).

Morphology | Morphometrics
soft rays: 9 - 12;
Vertebrae: 35 - 37. Diagnosis: Afronemacheilus abyssinicus is distinguished from its congener A. kaffa by having usually 8 or 9 branched dorsal-fin rays (vs. usually 7); the anterior and posterior nares closely spaced (vs. well separated); the intestine straight (vs. with a single small loop), no contact between sphenotic and epiotic (vs. usually in contact); two pairs of pharyngobranchials and usually three basibranchials (vs. three and four, respectively); the dark spots on flank small and irregular becoming larger and transversely extended on dorsum (Ref. 94278).
Found on the bottom of Lake Tana and in patches of macrophytes along the shore of the lake, and along the banks of the Blue Nile (Ref. 94278).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±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).
