Etymology: Steatocranus: Greek, steatos = hard fat + Greek, kranion = skull (Ref. 45335). More on authors: Roberts & Stewart.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 24°C - 27°C (Ref. 2059)
Africa: Mbomou/Mbomu River, tributary of the Ubangi River (middle Congo River basin), in Central African Republic (Ref. 42510, 52307). May have a wider distribution (Ref. 52307).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.3 cm male/unsexed; (Ref. 5696)
Rheophilic; pair-bonding and cave spawning species; in contrast to congeners, it seems the male guards eggs and
wrigglers, while the female is primarily engaged in defending the territory (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 (tm<1).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
