Etymology: Steatocranus: Greek, steatos = hard fat + Greek, kranion = skull (Ref. 45335); bleheri: Named in honor of the collector of the holotype, Heiko Bleher of Neu Isenburg, Germany (Ref. 42983).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 21°C - 27°C (Ref. 42983)
Africa: only known from the Kafubu River system (Luapula drainage, upper Congo River basin), Democratic Republic of the Congo (Ref. 42983).

Morphology | Morphometrics
(total): 20 - 21;
soft rays: 6 - 7;
Vertebrae: 28 - 29. Diagnosis: relatively deep-bodied species with a steep, straight forehead (Ref. 42983, 52307) and short snout (Ref. 52307). Very flat gibbosity, most pronounced in adult males; lower pharyngeal bone with 151 teeth (mean value); usually 5 broad gill rakers on lower limb of first arch (Ref. 42983).
Inhabits clear flowing water with rocks, in river pools; found in small groups, up to 20 individuals (Ref. 42983). Likely a pair-bonding, cave-spawning species (Ref. 52307).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
